So, its not converting an old laptop charger, it has nothing to do with a laptop charger short of using it as a project box :) Still, its neat to see how simple the concept actually is !
As an electrical engineer with an RF background, my forehead is sore from all the facepalming I did watching this. You would be better off simply taking that original piece of wire and sticking it into the antenna connector on the back of the TV.
I`m calling Fake on this one as he actually never shows disconecting the original service from the back of the TV and pluging this in showing that .. Hidden source , not this Antena pluged in on the back ..
Why did this idiot name his channel "Digital Sat Pro" there is nothing about Satellite TV on it, just a bunch of overly labor intensive TV antenna projects!
With the way things are going these days, with price gouging, and items being way more expensive than they should be. I think a lot more people are going to have to learn to do things like this. Very cool. 👍
Its not difficult. It is no different than the older TV's. it's a marketing gimmick putting Digital on the package to make you think it is different than what you may already have. Although depending on where you live an RF Amp may be needed to increase the signal which is what I though he was going to use the PS for. Again no different than the older TV's
Although these antennas would not work for me due to the fact I live over 100 miles from a tower, I enjoy watching you construct the different models. Maybe if I move closer to the city I will try to make this model, or I might make one for someone within range of the tower. Thanks
I've like to suggest using a "step drill" when drilling thin plastic, to avoid the all-too-common "grab" when a drill bit meant for metal breaks through! The step drill also deburrs the hole "automatically" !
You can recommend them all you like, not everyone likes stepper bits, and some tend to drill too far. v you have to know how to use the correctly for them to be effective.
When I was a kid, back in the 70s, my dad made an antenna from a coat hanger. He bent it into a circle and fastened it to the antenna input on back of the tv. it picked up a signal from a place called alfa Sentoria of the crab nebula. it was a foreign channel with funny looking people that glowed in the dark and talked backwards. Man, the 70s were fun.
i seen another vid from this same guy, he proceded to screw a spark pug up his ass, cross two fillings in the left side of his mouth with a paper clip, then stuck his right index finger up his left nostril and picked up some shit from the north pole, hosted by some fat ass in a funny red suit that hollered you aint getting shit then it all went black
Just exposing about 7" of center conductor on a piece of TV coax and plugging the other end into my TV allows me to get all 42 local channels. It's not hard to pick up TV channels, people.
I remember before digital TV, the best antenna, better than anything you could buy at the store, was a paper clip, bent into a ring with a tail. You'd stick the tail part in the antenna connector, and suddenly have more channels than ever before.
ב''ה, still a thing though you'll want to look at the standard size of a UHF loop, as that's essentially what you're making. In an urban environment very close to transmitters (Manhattan for example) the ridiculously small and out of tune paperclip may prevent overload and actually improve reception including with ATSC digital.
It certainly "looks" like an antenna. I assume that there is no consideration of the bandwidth of the signals that are trying to be received and the length of the antenna components. The proximity to the transmitter necessary for this to work could be equally achieved by a single wire.
The TV is close enough to the terrestrial tower, a piece of wire pushed into the antenna connector would work also. No dipole needed. Wire clothes hanger?
Sorry, this may work for short distances, but I’m 80 miles from downtown Chicago. I currently have an antenna that I bought in 1988. It is about 20’ long and 18’ wide in the rear. I use a 4 watt booster and get about 70 local channels. I have dish and it works quite well, however my antenna works better on the local channels. During rain/snow, the antenna works, but not dish.

So its not a charger that is converted, but its box! A bit disappointing, I had expected an active antenna with an in-line amplifier. After all the video title mentions the word "powerful" and the charger is indeed a power source. Turned out a clickbait.
Yes... this or a number of other DIY antenna ideas will work just fine. Problem is, you have to be fairly close to the antenna farm transmitting the video OTA.
so measurements must not be too much of a deal because my laptop charger is much bigger, and all you're doing is using a box to hold the stuff.Also it cant be too powerful because you moved it and it cut out. Would it not be better to have the internal wires shielded in the box?
They still have "Air Wave" TV. Holy Shit I thought that died out a little while back. Having a television with one antenna back in the 80s was rough livin.
I simple question, ok u able to create a signal catcher that found tnt too, how ur device handshake with it, they had vlans groups that include ports & those ports need to bind with the DTH number, even the feild guy can't do that, he need to report the instalation done this is the no bind it plz, the server admin bind it.
i know shit about coax and i got my own tv methods which dont need cable ...but this is still an idea for many things i think ....5 stars... sir i salute u and will run with the box and connection for sumthin crafty.
When I saw the title to this video, I thought, "This is nuts!"! But after watching it, it's definitely for real. Two comments: 1) At 12:34, did that HURT?...heh, heh...been there, myself! 2) I'd recommend a more powerful soldering iron for soldering those antennas.
So you reused a plastic box to make a double set of bunny ears? Maybe include some signal gain comparisons to support your claim of "powerful". Maybe include something about intended frequencies. Though from looking at it - appears to be AF/FM and over the air TV type signal range. You did a neat job of the actual construction.
Antena is beautifully built but how were the channel renamed with their original names displayed on Tv. RF channels comes only with number ..and RF antena always have some noise stripes and other flickering issues it cant be crystal clear like the Satteilite Reciver.. i can see clearly the sattelite reciver menu here.
While interesting to watch, the same signal can be received with a single wire "coat hanger" or copper wire, and not waste the coax connectors, or breath in toxic plastic fumes.
wow, i really thought he will be using the adapter components, if only using the case, the title could be anything "Turn a cornflakes box in to a powerful antenna..." or "Turn your mom needle box....."
Unless I missed something, there is no way the cable end (11:02-right) will fit onto the TV. The back of most TVs have Female Coaxial Port (center lead is much smaller than shown).
looking at a regional or age related varation in TV standards. I've seen RCA/component in 2 varieties, Coax, HDMI, Antenna (pair of screws), S-Video... too many standards... What he's got is possibly Composit Video...
@@Neuralatrophy Look a little harder. No one is using RCA, HDMI, or S-Video connectors to receive an antenna signal. His connector is obviously RF coax with a thicker center pin on the TV end. It's probably a standard in his region.
I would have used a 75 ohm balun inside. Also you don't have to destroy a charging power supply to make this a plastic construction box would also work. This antenna will work in local areas don't expect it in fringe areas. An old UHF antenna works better and you can add vhf elements and maybe use rabbit ears rods which will help with low frequency channels. Goto the tv stations website for exact frequencies the channel number doesn't give you a frequency like in the old days. Most digital channels are on UHF. Some on high VHF and few on Low VHF. 73
The shield isn’t always a ground connection. It’s a shield and commonly half of the connection to most antennas. What has been built is what is known as a “dipole” which is has a negative pole and a positive pole. This fellow’s antenna could be more effective if the shielded radials were pointed in the opposite direction as the radials on the center pin side.
@@LiquidRadio it is if it's cable tv. I used it when there were no grounds on the outlets. I had a surge protector outlet with lights and used the cable ground. It's also a ground when hooked to an outside antenna because of the grounding block. The only time it ain't grounded if the TV only has two lines to the plug and if you don't ground your outside antenna which I don't recommend. If the TV is grounded the antenna jack is grounded but still part of the antenna. Using a balun is the best way to match an antenna to the set. I know it will work better if you use a balun in this setup. I will try it when I find another set of rabbit ears. I know I have a few sets lying around. 73 PS you can also use wifi antennas from older routers, you will have to use sma connectors instead of f connectors. 73
@@ronb6182 Thanks... I was addressing the original poster's question, trying to keep it simple and without getting too much into explanation of details like voltage phases, impedance, common mode currents etc... 73
Not precise, because it must be super shielded in your design first connect small wire is open in air so it will disturb the signal, as soon as main wire gets open in air, where the shielding end, the signal immediately transmitter in to air.
Ok haters, now that I watched it to the end, which you should also, I see that he made a directional antenna. He doesn't mention that the length of those antennas are critical, and also that the metal lining of the case is critical, which is why he used a laptop charger case. I can't be sure without more information. Like exact dimensions of everything, but I would wager that he's getting at least 6 dB amplification from his directional antenna. Remember that we are now using digital signals, not analog, so the rules of the game have changed and the analog ghosting that would happen with this unit, is now an additive result, or multiplication? I'm rusty at this stuff. I've got a yaggi design in my head that's trying to be my dominant thought process that got triggered by his design.
its a bit like not having mu metal casing on the tuner box of an old tv set it be sensitive to stray emf i remember in the old days you always knew when there was a car coming or going up the road you get interference on the raster that's why they put filters on in the end but i was only kid then the days of valves thermionic etc
