[Elecraft] potential of static damage

[Bob - AG5Q]

When a transmission line is completely disconnected, there may be a charge build-up.
I've seen this happen even in a light rain with no lightening activity present.

When connecting an antenna, short the center conductor before sticking it in 
the antenna connector.  The xcvr's internal resistance to ground can probably prevent 
a gradual voltage build-up after the antenna is connected, but the capacitance
of the already charged up transmission line may give it a big jolt.
