It is only getting in via the TV coax.
Our home is all-steel, walls and roof, so there
is nearly zero chance I am getting into the amp
any other way - indeed when I disconnect the antenna
feedline and keep the amp on there is no interference.
It really appears that I need a 6M trap in the
feedline from the TV antenna to the amp.
WDYT?
