Usually, we had in our club, believed the presence of a Red Cross DC
grounded ground plane antenna atop the club tower did provide a static bleed
off. There have been confirmed sightings of minor "hits" to the ground
plane during other storms before we lost the VHF rig, and a power supply to
the coax shield hit.
We are planning on pulling off the antenna stack of GP and beams, and
putting a better ground path around the rotator. We suspect the DC path of
the GP may have been degraded in a hit.
A grounded tower usually provides a "cone of protection" around the area
where the tower sits. It does this by constantly bleeding off charges
accumulating at the top.
