17:00 counterpose will help. Easy to add to the SMA since it is is bare metall 18:00 those antennas can be called collinear antenna. It makes top and bottom flat and receives on the horizontal plane as you explained. We use collinear antennas on marine VHF antennas. More gain bigger antenna it is. You can make it out of coax cable. Many elements soldered together. And it has its own ground plane as I understand it.

We got 8.7 miles between 2 nodes yesterday with successful communication with the stock antennas. One node was in town in a fairly dense area and one node was out of town, just barely above roof line. Going to try and get 14 miles plus out of them tonight!

@ClacKeyTech 6 месяцев назад

did it work? 9 miles is exactly the range at i want to operate it but probably with more interference

@shaneciccarelli-palmer2962 5 месяцев назад

@shaneciccarelli-palmer2962 yes, sorry. We got 14.7 miles out of them with stock antennas no problem. We are working on getting some antenna that we can mount on the roof of our houses and see about 47 miles here soon now haha

I remember when to get more range you had to contact someone with an alias on the radio. Then go wait at the truck stop with cash in a envelope for someone to show up with your linear amp that may or may not work

Thanks for the heads-up on the AliExpress antenna's! Found the model for 5,72 (euros) each and paid just 16 for 2 antenne's and two pigtails. There are practically no nodes where I live and it's a very hilly province so I hope to be able to eventually get some solar powered repeaters on the roofs of flats/high buildings :D

@kurtdobson 24 дня назад

I’ve tested many 915 MHz antennas using a VNA. Most are junk and are not resonant at 907 MHz, which is the default channel. A simple dipole trimmed for resonance works fine. There are quality antennas out there with gain that work great and I routinely get 40 to 50 miles with nodes that have the better SX1262 radio chip. But remember the whole purpose of the mesh is to pass packets in hops between other nodes.

@ethidium8954 3 месяца назад

The little stock antennas that came with my Heltec V3 are perfectly matched. No idea why everyone says they are not. But in terms of gain, even a simple dipole made with a SMA to screw terminal adapter is way better.

@Meshtastic 3 месяца назад

It can be pretty hit or miss. Most of the time it appears to be a miss. There's a been a few lucky ones like you though.

@krakers665 Год назад

I'm newbie in this topic, but after watching this video I think about setup (868mhz): - for carring with me: t-echo with lynx dipole antenna - for powered setup on the roof of the home placed on top of the hill: rak wireless with hydra board and Rockland antenna - for car mounted one: t-echo with magnetized monopole antenna I'm not sure if I understood you correctly. Is this a good choice or would you do something different?

Hi Ben, i was hoping this would cover interpretation of the apps SNR & RSSI. The link budget was good to know thanks. Can you have different presets for different channels?

@Meshtastic 3 месяца назад

No, the presets are per device, not channel. So whichever preset you have selected is what will be used for that device.

@Number4lead 8 месяцев назад

A unit with a removable antenna where you can plug in a coax to an external antenna would go a looong way.

@catalinalb1722 Год назад

Hello, I have used meshtasting in the past between two TTGO T_Beam LoRA devices. My question is: Are there some public channels where I could find other users and just start a chat ? Thank you

@Meshtastic Год назад

Most users will use the default channel for their region as a sort of public channel. There's also those that connect to the public MQTT server. There's also a recent Matrix integration you can check out on Discourse.

This one is the first generation, which is very affordable and works well. The new V2 line is even more capable at a higher price point. I recommend sourcing one from one of the official vendors to avoid purchasing dubious clones that may not give you consistent or accurate measurements.

@TankJockey38 Год назад

I've yet to get 1 mile of range in a residential area. Even with a lynx antenna.

@Meshtastic Год назад

You've made a good step switching to a well tuned antenna. Now try getting one of your nodes as high above the ground as possible. This can make a huge difference in achievable distance. Two devices a few feet off of the ground will generally not achieve very much distance in urban / sub-urban environments. Also if you're on SX1276 based devices, as mentioned in the video, I recommend upgrading to SX1262 based ones and setting the lora.sx126x_rx_boosted_gain config. It makes a considerable difference in my experience.

@DevineState 8 месяцев назад

It's very well possible that there are no other users in your area, or if there are they are not using any of the default settings. There's a large group of user's that operate private mesh networks.

@nikandr23 5 дней назад

soooo 1. use LONG SLOW (right???) 2. sx1262 with option "more power!!!" 3. better antenna 4. ... on the mast?

@Meshtastic День назад

If you're specific use-case calls for long slow, yes. Otherwise sticking with Long Fast is usually fine. We've seen some pretty great distances on it. The rest look good too.

@mwngw 5 месяцев назад

This very subject has prevented my purchase so far. I need 5-6 miles range with some tree obstructions and no buildings over 2 stories point to point. My elevation is about 50' above family members I'd want to communicate with in an emergency. Per your coverage map, one other mesh device exists within 30 miles. Would I be able to achieve comm with an add-on antenna? Edit...why are these units not sold fully assembled?

@Meshtastic 4 месяца назад

We do not have a coverage map. There is a map that is passed around that is all user-generated data. This data is at best unreliable. 30 miles is definitely doable with proper line of sight. These devices are off-the-shelf devices adapted to our use-case. There are community members that sell fully assembled devices if you'd like though. You can search "Meshtastic" on Etsy.

That's definitely rough. We don't make the devices though, we use off-the-shelf devices. There are different frequency bands that are used for different reasons outside of Meshtastic.
