Convert LNB to the most powerful antenna on earth to receive terrestrial TNT HD channels

[freespeech]

Wow it works amazing, i can now get tv stations from outer space,

[jimnunya]

It is best to change the angle of the dish as well.
The dish will be set/tilted to roughly 30deg +/- 5 or 10 depending on the prior use.
You want horizontal for best terrestrial signals!
To be more honest and clear, the 'dish' portion will be nearly up & down vertical, by that I don't mean like a 'bird bath' but more like the LNB/antenna will actually face down a bit.
As is shown in this video, the dish or signal reflector is not bouncing the signals from ground stations to antenna, it's still bouncing signals from space to antenna!!!

A length of wet string will work just as well, if you are close enough to that TX

I have a tv in my bedroom that I had a hard time getting an antenna to work. I ended up taking a 8ft piece of coaxial cable, cut 1 end off. Stripped it back about 8 inches. Then hung the stripped end over the curtain rod. Works great and have used it for 2 years. As far as believing just about anything, keep your foolish comments to your self until you have tried it. Sure there are things on here that is click bait, but there are some things that do actually work. Don't be so narrow minded.

Good design idea but, there is a flaw!
Your Center red wire was grounded to the LNB body. You can see it at 2:25. Again at 2:31. You covered it up with the cap while it was still grounded to the body at 2:36.
I was waiting for you to place some shrink tube over it, but you didn't?
There's really no need to continue with all the different wires after that point.
Again, it was a good idea design.
But you have to keep the center wire & the ground (body) separate for it to be really effective, from start to finish all the way through !👍

Why not modify the actual LNB too? Get rid of the filter & downconverter, and use the amplifier! You won't get much gain at VHF & UHF off those tiny Ku dishes! Parabolic dish gain is a function of dish size to wavelength, and you need > 8 wavelengths diameter to get good gain.

I suspect a better arrangement would be to just fix a folded dipole to the LNB arm to be honest. As shown, Soldering all four legs together means two elements would act like stubs!

Wow i did this now i get super clear live images from the james webb!

[TedHallII]

Throwing away yhe most useful part and just using the shell told me all I needed to know about this project

[richardsmith]

PLUS If you paint the dish with enamel paint, it will reflect more channels

[dandantv]

Thanks you my friend good work...Sat pro

The video should be titled "How to destroy a perfectly working LNB unit".🤣
Check at @1:21 . He didn't remove the solder from the connection on the bottom part, breaking the board... At @1:26 it's clearly visible how he snapped the board entirely and basically destroyed a working LNB...
I bet he didn't watch television for quite some time after that...

[batsonelectronics]

the trick here is that the station broadcasting is likely a mile away and no obstructions. He is in a heavily populated area and that is where they tend to put the transmitters to reach the most people. I could get NYC stations in NJ with a tiny antenna because it was clear line of site and not far. Same thing is likely happening here. Those are High Channel UHF elements he just made.

[guinamos]

Thank you very much. That works for me really good.

[SerpentOfTheWound]

Sounds like you got the bang-bang family below you there.😁

[steveaspen]

No. Definitely no. It needs a decoder, amplifier and signal repeater, found in the electronic board that he took out of the unit, so he connected regular cable to a cable service box and deceived the masses.
Try duplicating it and you'll see.

[andyhowlett]

What a load of crap. Takes apart a genuinely powerful LNB and builds a really bad UHF antenna that will only receive local transmitters. For a few pennies you can buy a real UHF Yagi that will out-perform this thing. There is so much ignorance in this world and it all seems to appear on You Tube.

[DAVIDGREGORYKERR]

I would have tried to mod the LNB circuit to change the frequency of operation into line with the band you were interested in rather then just throw away the board.

Estas masacrando a la pobre radio electrónica

[duotronic]

This guy ran out of IEDs to build. Kinda surprised he has all his fingers.
