[SixClub] Protecting preamp

[K8RI on 50MHz]

I have a pair of UHF TV antennas at close to 90 feet with the tribander at 
100, the 7L 6-meter beam at 115 and vertically polarized 144 and 440 arrays 
at 130.  Actually I'd like to mount the pair of UHF TV antennas some where 
between the 6-meter antenna at 115 feet and the 144/440 arrays at 130 feet 
which is probably not practical.

I need to do something about protecting the preamps for the TV antennas.  A 
high pass filter might work for 6-meters, but 144 and 440 are something 
else.   The antennas are already too close and I'm going to be raising the 
power as well.

Any thought/suggestions on how to protect those preamps.  It's a real bear 
to have to climb to the top of the tower to replace them.
