I have the Mark V Field. I have been using a homebrewed 2 foot diameter 
unshielded indoor box loop for receiving and have never had a problem with RF 
getting back into the receiver to damage the front end, even though the 
transmit antenna is very close by.

But now I have purchased the 8 foot diameter outdoor 160 meter coaxial magnetic 
loop antenna made by KC2TX for receiving plus the KD9SV 160 meter preamplifier. 
I'm on 1/4 acreville and the loop will be mounted on a push up pole at 25 feet 
and unfortunately within 100 feet of the 160 meter inverted L transmitting up 
to 1000 watts PEP. I now wonder if I'm increasing the danger of damaging the 
front end of the V Field and should I put a front end saver device in line like 
the one KD9SV also makes?!

It seems that somewhere on an email reflector this issue has been discussed in 
the distant past and I seem to remember some saying yes use a front end saver 
and others say no the auto switching circuitry in the Mark V will handle the 
potential incoming RF. Any comments/personal experiences would be much
