I have one special low band receive antenna that I need to
protect. I use a grain of wheat bulb in series with the antenna
with two back-to-back 1N5818 Schottky Diodes (low Vf) to ground
on the receiver side.
You can use a receiver protector on the main TX antenna of a
transceiver, but the
uate even running an amp.

He said that he has a protector on the Beverage. The RG5000HD is for
receive antennas only so it will not work when he listens using his TX
antenna on 10m-30m.

Be careful, and make a few checks to avoid surprises.

The K3 is pretty well protected -- if, for example, you hit it with too
much signal, the attenuator will kick in and the preamp will turn off.
And if that doesn't reduce the signal eno

This discussion has made me curious -- especially when I carry my KX3
around at field day -- how much signal is safe and how much can do physical
front end damage?

If you're worried about burning out the receiver front end, why not test
it? Add a 20 dB (or more) attenuator in front of the receiver and have
your neighbor try transmitting on all bands and antennas. The K3 S
meter is pretty accurate. Just add 20 dB to the reading to see how much
RF is com
I have seen how effecttive item #5 is on the previous post.
And if you don't follow all of Jim's advice then you are really missing
out.
I have seen companies spend thousands of dollars for advice that you just
got for free.
