Hello Bill,
Use a larger antenna that won't need a preamp to get the signals. Those wide
band preamps collapse in the presence of high energy RF.
At my home the TV can be used while an 8877 amp on 6M and an 8877 amp on 2M
is being used. The answer? NO PREAMPS! The TV antenna is pointing away from
the ham antennas.
No problems here.....
73,

Subject: [RFI] 1500 Watts vs. Radio Shack Amplified Antenna
My neighbor who lives 55 feet away from me has a Radio Shack Amplified
Antenna.
This thing looks like a real big Frisbee.....it is round and has a wide band
amplifier built into the housing. No problem with my Icom 765 running 120
watts, but when I turn on the L-4 B, I obviously totally wipe him out.
Personally, I don't think there is any possible way I can prevent this from
happening. I don't know how wide the pre-amp is but it most probably picks
up
20 meters. So.....with a TV signal in the microvolts being mixed with a 10
thru
20 meter signal in the 1000+ watts range being mixed together in the pre
amp,
there isn't any doubt in my mind what gets presented to the TV set. I
really do
not see any hope for this situation. I cannot get to the preamp and I don't
really think putting a high pass filter at the TV set will do any good
either.
I of course am using a low pass filter. I haven't tried lowering my power
from
the L-4B lower than about 700 watts and I still cause problems. Other than
offering to buy him a cable TV installation, does anyone have any
suggestions
how to handle this situation?
Thanks,
Bill WX8S
