Maybe consider also installing a postal tube for launching SSDs across. Load it up, pack it into a tube cartridge, *thwomp*, it's vacuumed over into the other building, unpack, plug it in, data transfer!

As a former tower tech and WISP guy, set the Tx to -4db and auto adjust power off. You'll get a better alignment that way, also some freaking HOT signals between the two lol. I'd also recommend getting a set of Cambium POE surge protectors. We use them on towers quite a bit and they have held up to literally lightning strikes over and over. Highly recommended. Suggestion #2: During high winds them mounts ain't gonna hold 😂 you need a 6x6ft full of bricks with the mast in the center Suggestion #3: Your LOS may be getting cut off by the parapet a bit, raise them about a foot or so higher and you'll get a significantly better quality in TX/RX.

they need to be higher, or at least on the edge of the rooftop, the signal is affected by the Fresnel zone Solution 1: a longer post. Solution 2: bring them closer to the edge of the roof, thus avoiding signal bounces and interference due to the proximity of the ground

Not tech related, but it shows he's gotta be a good boss when he takes responsibility for the wrench incident instead of blaming it on the person that threw it.

The speed jumping to 1Gbit and then higher is probably the dishes jumping between 5GHz and 60Ghz. VHT160 5Ghz is about 800-950mbit. Probably look at getting both of the dishes mounted higher, likely the fresnel zone is getting cut off being so low to the roof.

I am certain a lot of us was terrified for a second and then incredibly impressed at how Linus was holding that laptop on the corner alone....and still didn't drop it.

I'm sure you guys know what you're doing so this info is maybe more useful to others that are installing PtP radios. I'd be curious what the signal gain is on the radio, -37dbi is quite high for that short of a link. Usually you'd want to aim for -50 to -60 if possible. You should make sure you aren't oversaturating the radios as too high output can cause the uplink and downlink to interfere with each other similar to someone shining a flashlight in your eye while trying to read words off a page. Also, performing a spectral analysis is a very useful step as well. The uplink and downlink carrier frequencies can't use the same frequency, so it's possible that one of those frequencies has more interference in the surrounding environment. You may be able to change to another channel to get closer to a 6G link and additionally choose a wider channel width if the interference in your area allows for it. Check to see what the MCS methods are for up and downlinks. If they aren't at 15 then you probably have an interference issue. Look into "fresnel zones", as others have mentioned, the edge of the building may be causing a problem with the vertical signal. Anyway I'm no expert but I've been installing Ubiquiti PtP for close to 5 years and that's just a few things I like to look into.

Just a tip for next time installing a wifi bridge, those thing need some clearance from the floor, technically you need to leave at least 80% of fresnel zone free (a imaginary elliptical tunnel), eyeballing the distance a bit at 60ghz is about 1 meter so a pole 1,5 to 2 meter should do the job, with the backup frequency at 5ghz is about at 3,6 meter. Also you should consider the reflection of the floor can inject into the wifi bridge but the irregular not metallic floor should be enough to ignore it. Hope it helps. Source? I installed few of those bad boys.

Always love a networking-related video, especially miss the old server vlogs

I love how Jake just chews Linus out for asking someone to throw the wrench up when the wrench hits someone's car XD he just doesn't hold back "You fucking idiots." Priceless

Funnily enough I used to work in the development department for a company in Scotland who are well known for selling used cars. The IT guy told me In their new build HQ they were still waiting for a connection from BT (British Telecoms) so in the meantime they used a building they owned not far away (literally across the road so I hear) which had a fibre link and set up a satellite link between the new HQ and that building. Worked very well.

Mad props to Linus you the man pulling that up alot of people scared of roofs plus pulling something like that up feels like 5X the weight that it is and pulls you real hard. I did alot of HVAC and pulling a twin scroll compressor onto the roof the same ways is real tuff and scary at the point when you have to move to grab it up. You did a supreme job so props again. Love u guys

Something to try. As backwards as it sounds, turn the broadcast power to the lowest setting, -4bd or so, since the distance is so short it could be distorting because it is too "hot"

The antennas are too close to the roof, so there is a substantial reduction in signal quality because fresnel zone... I bet raising the antennas 3 more feet will make the connection even faster... Also since those antennas are rated for long ranged you should reduce the power to the bare minimum... I bet Ubiquiti can help tune them for you

"we don't have walkie-talkies today" says Linus while holding his PHONE in his hand, then the camera cuts to Jake who also has his phone is his hand, and yet they still shout to each other

I love the Linus / Jake synergy. The roasting is just hard enough and not over the line. Makes me addicted even more than before.

Nothing I like more than a 20+ minute video with Jake and Linus installing networking gear, seriously

I work at a company where are core infrastructure is providing wireless internet options as a network provider. This solution is diffidently 1000% overkill, but I love it

please more networking stuff ! I really enjoy these kind of videos from LTT

I used to run the network on a campus that had six buildings with Ubiquiti Wi-Fi bridges between them and they were rock solid. One pair was even some of their oldest 100Mbps units that were in operation for probably close to a decade.

Linus: "But that would cost money and I already spent it all" Yvonne: "I will send you a house warming gift"

I could watch a whole channels worth of Jake and Linus' networking adventures, they're always the best videos lol

I love these vids with Linus and Jake… ultra crazy DIY. Amazing. Please never stop.

I have only the vaguest idea of what they are doing but I watched the whole thing cause I absolutely enjoy watching them do it. Would love to have this must fun on a project.

I installed a few older models of these a couple of years ago, not the 60 ghz one, but 5 ghz and 20 ghz. What I think is happening here is the 5 ghz is connecting well but the 60 is not. The 5Ghz is giving you the 1 gigabit and every now and then the 60 happens to connect and give you more. At that range the 60 beam would be so tight it would probably just be like 2-5 cm. The farther away you are the wider the beam spreads so being too close can make it harder to align. As you got 3 gigabit for a while you are probably really close to the 60 working, it just needs to be fine tuned. The dips below a gigabit that you were getting are probably from the Fresnel zone of the 5 ghz, it would be around 2 meters at that range, so it is bouncing off of the roof a bit. Ideally your dishes need to be a bit higher up, but that would not matter if the 60 was connecting solidly, as it's Fresnel zone would be less then .5 meters at that range. To get the 60 aligned I would recommend to set up a script that keeps a constant file transfer going and a way for you to monitor the speed while you are on the roof, then to just turn the knobs on the dish a tiny amount at a time from both sides. Wait a bit to see if anything changes then keep doing it until you get it. Considering how tight a 60 ghz beam is it could take hours. I never worked with anything more then 20Ghz and even that was a pain sometimes. With 5 ghz you can usually just eye it and it is fine, but it can take hours to get a 20 lined up well, especially if you are too close. One time on a close 20 ghz link it took us 3+ hours to get it aligned and you guys are even closer and using 60, so it could be really tedious. I really wish that this sort of dish came with a perfectly aligned laser mounting point on them, so you could clip on a laser dot and just line up the dot to a target point on the other dish.

This style of video is great to get from you guys sometimes. More laid back, some more bleeps, and messing around. Just a couple tech nerds yelling at each other while setting up tech. Loved it.

5:07 I used to carry large dishes and cinder blocks up on roofs like that a lot, usually we took a long rope and tied the object in the middle and had one person up top pulling up while the other would lightly hold the other end about 15 feet away from the building and keep the object from scraping the side of the building, this worked pretty well but it certainly gets to be a struggle after a while once you have to haul a dish, sled and 8 cinder blocks up

I did this back in 2012 when we had 3 units in the same complex, two were next door to each other and one was around 600 ft away across the parking lot...Worked great for a couple of years, the building only had crappy copper wiring that was falling apart so we had to run our own copper back to the MPOE so we didn't even have another option really of getting a second connection.

That dish alignment could have been so much "user friendly" with a strong laser pointer.

im calling it, give linus 10-20 years time he will practically own that entire industrial / commercial complex

Thanks for sharing your experience Linus and the team ❤️❤️❤️

Idk why but it just makes me so happy to see you guys grow and have so much fun. I love seeing people succeed.

I just wanted to note that that radio has an SFP+ port and they installed an ethernet module. While it works, given the opportunity I would have suggested using fiber modules instead. Lightning can't travel over fiber. You would still need to provide the 1G POE connection to power the radio but that is much easier to send off to an isolated switch and not plugged into the main network. Fiber is way better than any lightning/surge arrestor that has ever been made.

As a server guy, please test the link speed with iperf. File transfers are always limited of disk speed and software limitations, but iperf is designed to be used as server to server speedtest, so shouldn’t have any such limits. And it is preinstalled on your TrueNas box. I believe that the sudden jump in speedtest net may be because the server you’re testing against has already some load and most people have higher download speed than upload so as the server likely has symmetric or fiber, there isn’t as much congestion in upload.

FYI physical alignment over that short a distance is much easier with a laser pointer and a target fixed to both dishes. simple easy and no guessing. i have done this several times for smaller distributed dishes on farm buildings separated by more than 250 yards

I loved that head wear made of wire!

Can only imagine the employees reaction when Linus walks up to them at their desk. "So listen. I hit your car with a wrench. Here's $1,000. Sorry."

It's crazy to see how fast you guys are growing. Almost 1 year ago, you did a studio tour and now you're adding 2 more units. 1 of them is just for MERCH. It's crazy!

I've done quite a few of these building to building dishes. Use a laser taped to the top of each dish to get the alignment right.

Man something about LTT vids just makes me happy. Thanks

Seeing how everyone is getting more comfortable/confident being on camera from where they first started. Shows how much everyone is growing as individuals. Great to see everyone finding their true roles

As someone who worked on roofs as a job and had fall certification for several years, I want to very much tell everyone DO NOT DO ANYTHING THEY'RE DOING IN THIS VIDEO lol

I really like the lighting on the rooftop

Those NPRM's are way under rated for that large of a dish. 2 cinder blocks vs the torque created by a light wind on that parabolic dish. You will be out of alignment first wind you get.

You know a 2 dollar laser would've helped aim them to align them perfectly.

Shout out to the crew that will come in once filming is done to clean up and seal it properly.

This video gave me a flashback to my days before getting into Computer Science. Used a IT Technical Support course as a stepping stone and we had to do Ethernet cables, making them from the wire and the connector. Mine ended up being like an inch or two long..it was horrible. Never looked back..

Fantastic video, as always! Definitely had to sign up for the Grammarly premium, lol. I figured supporting a channel that I've literally watched for years was the least I could do.

14:10 my heart rate took a lil jump watching Linus handle that laptop

I will never not love Linus and Jake's antics, truly the highlight of this video Edit: Linus (the child) getting Jake (the responsible adult) to actually throw him his wrench and it still falling, and hitting someone's car is genuinely the best thing I've seen this week and it's only fucking Monday

Love seeing RF related videos from you guys.

these infrastructure videos with Linus and Jake are my favourite LTT videos

Used to work in line of sight comms. The comments about increasing the height and reducing the transmit power of the antennas are correct. and at this distance, the fine alignment needs to be done really slowly, like maybe 1/8th of a turn of the knob, not several turns at once.

As a local vancouver roofer I feel like letting you know you should be putting type 4 extruded insulation down under those things on the roof without a layer of insulation for protection itl break through the rubber over time. haveing it on the rocks would be better then not haveing them. Also dont let worksafe see this video they would love to fine ya for working next to the edge without proper fall protection.

For this microwave Connection you should use an higher Pole because of fressnel zone of 15° in the coil, you might can get reflections. When it rains it should modulate down and work further. But nice to see, iam working with these technigues in germany for mobile phone providers :)

This might be the most Canadian I've heard you guys sound and I'm here for it

Love how they both walk with their little backpacks. Fells like two schoolkid friends going home or so.

My anxiety when Linus shifted position to LEAN OVER THE LEDGE to grab the dish-- 10/10 would panic on behalf of another human again.

I don't get everything you guys talk about in your various videos, but, I love the ones where you're "doin' stuff!"

I would love to work with Linus! His sarcasm and dark humor make this 100x better than any other tech channel.

Something to note, with these ballasted EPDM roofs I would highly recommend putting a rubber pad beneath those dish stands. The membranes are pretty thin and leaks can run underneath the membrane which makes it very difficult to locate leaks, putting down pads could save major headaches in the future.

i love how towards the end aligning the dishes they're yelling at each other over the rooftops while holding phones.. big brain battery saving strat boys 👍

After seeing The New Guy in like five videos now I am overflowing with glee every time I see him now. Which I'm very glad about because Linus has had some great people come and go and I'm glad to see someone I like so much that seems to be sticking around! :D

I can't beleive I missed this video when it came out!

Love how Steve from GN has everyone wear safety glasses to use a stapler. LTT- "everyone, let's fuck-arse about on the roof of the building"

Jake and Linus videos are always so fun to watch. You two are the perfect kind of no-filter-chaos xD

the mix between sketch and legitimacy with this install is the perfect balance, and is exactly what i expect from LMG.

I love seeing you guys use Ubiquiti stuff! If you want to try another good product for PTP "air fiber", the Mimosa B24 is great. Gig speed but less worry about rain fade and a MUCH smaller footprint.

The like 30 seconds of Linus talking from the perspective of the Ethernet cable may be the best content this channel has ever uploaded.

"Come with me, and you'll be in a world of OSHA violations"

This is a level of DIY I think any of us techy types can identify with. Cranes? Hoists? Nah, rope and out of shape computer geeks. Love it.

Nice to see you'll are moving up congrats guys I always enjoyed you'lls tech shows 😎🤟 definitely a nice idea for free internet especially if your old building is right next to you

I install these dishes for a living, typically with a dish like that -36 is as good as you can, unless you raised the pole for less building interference. Good job!! :)

I'm guessing that LTT doesn't have a safety department. That step ladder use would get our safety staff in knots. ETA: ok, that wasn't even the worst issue.

I work with UBI systems often this was awesome to watch ! Nice job on the alignment UISP can be a pain lol

Honestly Guys! For ALL the tech knowledge you deal with.... Your "installation skills and methods" are primative!

18:30 I'm almost certain that these antenas were placed to close to the roof. If these work in 60GHz band then first Fresnel sphere in half distance of 50meters should have radius of about 35cm. But in 5GHz mode it is about 1.2 meters and that antenas are much lower over the roof.

Linus made a great point about ISPs, I have at&t and its a huge pain

I love that the logistics department handled getting the cable over there, but the little bossman is the one lugging a dish that rivals his size onto the roof.

It's all about modulation. Do a link planner get expected signal and line them up with scopes and fine tune. If your over 10 off expected signal your on a side lobe which is crazy easy to do on millimeter wave by the way. Once you've achieved the best possible signal is when you tweak the eirp and power output to achieve the best modulation. With 5g a -50 is more or less best practice but with and mm wave you want that extra oomph to mitigate rain fade, especially if it's your only connection. But as close as it is rain fade should be minimal. Just my 2 cents. Been installing ubnt gear since around 2010 when they came out.

Jake has gotten so much more entertaining, and, to be frank, not annoying in these vids since his early days.

Hey Linus you need a earth cable to the earth point on the lighting protection for it to work

Great video, was really wonderful! Can you do a follow-up video, where you put the dishes closer to the edges of the roofs? It might be that the dishes use e.g. horizontal polarisation for the one direction and vertical for the other. In this case the waves are differently scattered and diffracted on the roof edges, which would explain the asymmetric speeds ;)

In high school I worked part-time as an equipment technician at a local radio station. The boss bought a "used" satellite dish from another radio station in a different city. This was a gigantic 12-15' aluminum dish on a heavy-duty mounting bracket. It was on the roof of a 6-storey building and my job was to help a contracted crane operator pick it up off the roof and lower it down on the ground to be disassembled. It was a very windy day on top of that 6-storey building and being 16 years old and stupid I tied a rope from the dish to my waist. Of course the instant the crane lifted the dish off its bracket it swung wildly in the wind -- yanking me off my feet and nearly pulling me up into the air above said 6-storey building. I remember hoping I tied the rope tightly because pretty soon I'd be dangling from it about 75' over the parking lot. But luckily the crane operator saw my situation and quickly lowered the dish back onto the roof. I was dragged across the roof pretty quickly but I never quite went airborne. Almost 40 years later I still think of that near-death experience every time I see a satellite dish or a crane.

When I was studying, I met a guy that lived in a rural area, he had such bad internet that he ended asking for a custom fiber installation in the hopes of reselling it to his neighbors using this same air-fiber tech, first 2 years or so were all losses, but now he's living out of it.

As someone who used to install a ton of Ubiquiti point-to-point equipment, I can verify this is 100% the Ubiquiti recommended installation process 😂

working for these guys must be the best job in the world lmao always f'in around yet making great content

i think an easy way to line them up really good would be to go up at night and use laser pointers attached to it or if it uses a view finder to point the laser though the view finder and you should get very accurate results

Imagine working near these guys and hearing this all day from the roof 😂 PS I'd park somewhere else if I saw them coming too :P

I love when Linus + Jake decide to momentarily go Hyper-Canada.

This should be a series. Like cribs

For anyone needing to set up their own pair of these….you actually do need to align them well, especially at closer distances. The signal is emitted in sort of a cone shape. It’s a bit more complicated than that but that’s a decent way to visualize it. This means the farther out you are, the wider the “cone” of signal, the more “play” you’ll have in alignment. The closer you are, the smaller the radius of the cone you have to work with. This is why Linus was able to line them up first-try when it was over a 3km distance. “We’re so close that it doesn’t really matter, maybe?” - this is the opposite of how they work.

At that distance it seems like they could have literally ran a fiber cable suspended between the two buildings. That's assuming it wouldn't violate local codes though.

I once inherited an infrared laser inter-building connection like that, and it sucked beyond any description I could use in writing. The two buildings had completely different construction types and therefore, expansion rates as temperatures changed, and to align it you had to put on infrared protective goggles, and use an IR sensitive "target" which made the dot visible - with one person on each roof (itself a complex arrangement on one end due to security arrangements), you then had to tweak the vernier screws on each mount to centre the infrared beam from each in the centre of the target receiver (which was only visible to the person on the other roof, so communication was essential - back in the early days of hand-portable cellphones this was a big deal, and our department had exactly two, never to be allowed out of the office, and just for doing this regular realignment. With all the incoming WAN connections in one building (256kkbit/s to larger sites and 64kbit/s to small ones) and the main servers in the other (political decision), it was a chronic single point of failure in the whole national network of a major utility. Twice a day, minimum, we had to adjust those cursed things and my first action on inheriting them from my predecessor (guess why I replaced him) was to order a pair of diversely routed dark fibre connections between the buildings, with suitable transceiver equipment to translate to our 16Mbit/s token ring between copper and fibre at each end. Network availability jumped from 55% (essentially unusable) to >99.9% instantly on the first of the pair of routes being commissioned, and I got a very nice bonus :-) We were never able to get to the magic 99.99% availability as occasionally the WAN links would reset :-( It was in making this suggestion at project meetings and having it dismissed by my predecessor (while the team manager was present) that I became a network manager - a considerable promotion. It has taken about a quarter of a century for the technology to be ready for prime-time deployment, and we were the poor suckers that were at the bleeding edge. I later deployed the very first token ring switch (developed by Madge) on the same network. I still kinda miss the graceful degradation of token-based networking over CSMA/CD which saturates exponentially but fully switched ethernet did cure pretty much all of that.

This is something I setup all the time for work, but we install them on towers and utilize band 43/48 too.

I wonder if having the dishes on higher poles would increase their abilities, honestly for that matter I wonder what speeds would have been like if they were placed point blank in front of each other. Maybe a minimal distance is required, but still basically wonder if they could have ever lived up to the max speeds they claim.

It's always nice to see the LTT folks having fun when working on stuff and making videos

Linus evolving from breaking his own computers to breaking other peoples cars XD

Much fun. Had me thinking of using a suction cup in the center of a dish with a good laser pointer in the middle of it to line the dishes up. Using safety glasses!
