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?
