The frequencies used by air craft, and police are right above the FM
band (what would be 109-120 on the dial or so), which is between
channels 6 and 7 in the TV spectrum.

So yes, a bad TV antenna product can cause problems with public safety.

yes, but there's no antenna in an amplifier.
let's say the amp is 10 cm long, if there's a 10cm trace on the PCB it could
radiate at 1.5Ghz, not 100MHz. I can see how someone outide your house can
pick up stray emissions, but I don't see how these emissions would reach an
aircraft 10Km above.
