Also, how about RFI problems associated with nearby transmitting antennas
that might cause RFI overload problems to the Dish or Direct TV systems - as in
TVI?
I would expect any issues to be the result of 1) noisy switching power
supplies, 2) noise from the downlink electronics, and 3) common mode
coupling on the coax (both TX and RX). and I would expect them to be
easily solved by winding turns around ferrite cores. I had DirecTV in
Chicago, and never had any issues, with antennas and DirecTV downlead in
close proximity (5-25 ft). I don't remember if I did anything with chokes.
