[TowerTalk] coaxial for jumpers and right angle connectors

[Wes]

These were 24" RG400, N male on one end, PL259 on the other.  Used outdoors to 
jump from a ground plate with SO239 Feedthrus to Heliax Type N female runs to 
the tower.  Purpose to disconnect lines for lightning protection, They both 
failed open, not sure if center conductor or shield. One failure manifested as 
loss of received signal strength that was "cured" by a dit at at 100W.

I can's say for sure, since I thought it was protected from such things, but my 
KPA500 failed somewhere in the PIN switching path. When I opened it up to 
troubleshoot, the ceramic lid from one of the FETs was laying in the bottom of 
the chassis.  Remarkably it still made full power.  Now it's on the bench with 
the power transformer removed, ready to ship back to the mother ship.
