Broadband TV amplifiers are darn near impossible to deal with. Your rig may be clean as a whistle, but when the RF from your signal down in the HF range hits that amplifier it overloads the first stage producing garbage across the spectrum, including all the TV channels up through UHF. Even TV's not connected to it may get TVI from the junk re-radiated by the amplifier through the antenna.
The right solution is a high-pass filter at the broadband amplifier input to block the HF signal from your rig, and perhaps proper shielding if it isn't already. That's not a practical solution in cases like yours in the RV park. The only other solution is to reduce the amount of RF it picks up. You do that by moving your transmit antenna away from the TV antenna and/or reducing power. Ron AC7AC -----Original Message----- Is anyone experiencing TVI. Recently I went camping in an RV park where most of the TV reception was via the Winguard amplified TV antenna, not Satellite. This is a broadband receiver amp for TVs and is built into the antenna. When operating 40 and 30 meters CW from a nearby picnic table into a Buddipole with close to 1:1 SWR I could see my own TV inside the motor home 15 feet away lightly flashing as I keyed. The problem was somewhat less with internal batteries indicating 1.5 watts but the dim flash was still there. Park folks not happy, me not happy, what is your experience??
