Re: jammers

A TV jammer is ilegal. If you have cable TV, you need very high jamming power to jam the channel.
However, if you use a classical antenna, like rabbit ears, you need just a simple sweept oscillator, that covers the respective channels, placed near the antenna.
For friends and family you don't use a jammer ).

You are partly in error. It is NOT illegal at all. Some watches (Casio) come with that feature to joke around with it. Maximum distance, however, is about 10 feet. Basically in close proximity of the TV.

Jamming your neighbour's TV is interfering with their right to watch whatever they want, but within the boundries of the law.

Re: jammers

simply, u can jamm anything in ur home & not others. If u hv some complaint with neibours, friends, solve with them peacefully. If they trouble u, then compaint to police. If u want to do this for fun, check that they don't compaint or fight with u.
U can use any sweep generators with high power cable tv amplifer with matching antenna at the output. The type of used antenna will be decisive factor in directivity of signals.

For satellite TV jamming the best tool is a simple blanket! Cover the parabolic antenna! Or simply the LNB with "invisible", small, Al foil.

The real electrical jamming will be expensive! The satellite broadcasting chanels are around 20 GHz. Considering that parabolic antennas has good side lobe cancellation, because narrow 3 dB angle, you need to pump it hard RF power for jamming.

Considering the prices of f>20 GHz amplifiers... Hmmmm

Nice job!
Try the blanket! Or try the IF of the LNB, around 800...900 MHz.

Maybe the cheapest solution is to disassamble an old microwave oven, and marrige it with a high gain helix beam antenna But forget this way if you want children and family! (sterilization side effect of 2.45 GHz microwave beam, or cancer or sudden death! NOT FUN!)
