I would put a high-value resistor - 10K or more - from the vertical
to ground. That should dissipate the static buildup AOK.

Is there any reason to choose one specification over another for the

appear to be GTE's vs whatever the kits came with in 2006.
I had thought that the frequent frying of these diodes on my k2 was due to
lightning strikes but it looks more like the product of static discharges via
my 23 foot vertical - you can hear the snaps as the potential arcs
across the
coax connection at my Balun. I had thought that this only happened
in storms
but it turns out to start as the storm is coming. Clearly the
answer is to
disconnect the radio from the antenna unless I'm using it. It's also been
suggested that I put an inductor shunt between the lead in and
ground, but I'm
at a loss to size it.
It also occurred to me to bring a wire up from the grounding system to about
the height of the antenna and put one of those wirebrush static wicks on it.
Is what I'm considering crazy? If you think so, it will be ok to tell me.
