[TowerTalk] entrance panels for grounding

[n4kg@juno.com]

The N4AR antenna farm (lots of towers, antennas, and high wires)
collects a lot of lightning.  Bill religously grounded his antennas
and radios and would still find fuses blown in the equipment.

When he floated his radios (no antenna or AC connections)
the blown fuse problem went away.
