[Yaesu] Receiver Front End Saver Question

[Thomas Giella KN4LF]

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 appreciated.
