[TenTec] Omni VI - test diodes

All true diode parameters concerns with the OEM diodes.  I wonder if 
anyone has investigated if the rigs with failing diodes are left plugged 
into antenna 24/7?  It might be accumulation of wind static or picking 
up the induction of a nearby lightning stroke that randomly claims a 
diode "victim".

A possible safety factor could be to place a high value carbon resistor 
from the coax center to shield, to discharge constantly, any static 
build up.

That might also work if the rig is operated by a ham who walks over a 
carpet in the ham shack, and then touches the rig.

A 150 k ohm resistance across the 50 ohm connection is not going to rob 
much power and in carbon; work well with RF at minimal cost.

What does the group think on that idea?
