TV jamming

>>58215449
A jammer blocking TV reception at short range can unintentionally emit second harmonics into the GPS bands, especially the L1 band, and at vast distances.

Experienced people spend a lot of effort making sure there are no harmonics. Unless you have a fair bit of equipment and frankly already the knowledge to make what you want you run a major risk in blocking critical infrastructure such as safety of life services.

I will leave it to your imagination to ponder what the consequences will be.

If you have a genuine interest in radio technology there are many designs on making for instance crystal radios and these are safe.

>he actually wants to jam with tv signals
For what purpose? Sure, this may be practical, but someone over there might conceive it as a "hijacking attempt" and report it to the police (unless you were using empty frequencies).

I lived in a peaceful unit complex until this shit moved in next door and blasts their TV 18 hours a day I went around and kindly asked them if they could turn it down. They completely dismissed my concern and turned their TV up louder and now leave it on 24 hours a day.

2 weeks later during a thunder storm I climbed up into the roof and disconnected the aerial. We share the same one and the splitter is on my side. This gave me a few days of peace until they bought an indoor aerial.

I don't care about the law anymore and as a single male I have no tenancy rights to quiet enjoyment, I know this from experience..

I wish you the best of luck, OP.
You should let us know how it pans out for you if youre successful

Question related:
How difficult would it be to transmit a video signal over the same frequency a TV channel does so I can output the video footage on a TV?
What hardware would I need?
Is it possible at all or would the two signals interfere and create artifacts?
I'm talking about close range like in my own house.

I found something:

Good luck with this!
