I'm in the process of building up a K9AY loop, using the Array Solutions
boxes, and it occurred to me that I probably need to work out some way
to protect the preamp in the shack-end box from transmitted RF,
particularly since the K9AY loop is only about 60 feet from the vertical
leg of my inverted L and I'll be running 1500 watts.
I can see maybe cutting off the DC to the preamp, but figure that won't
be enough. Alternatively, I can probably work out a way to either open
or short the feedline coming into the indoor box where the preamp is.
Any advice as to which would be best (opening or shorting)? I only have
one spare transistor.
Advice much appreciated
