[RFI] 6M Getting into TV Channel 3 - CLARIFIED!

[kd4e]

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?
