Folks,

Do not be complacent about static coming in from the antenna in the winter.
Even though there may be no lightning - wind, rain or snow can build up 
a very large static charge.

I am not saying that was Brian's situation, but be aware that 
possibility does exist.

Make certain there is a DC path across your feedlines to bleed off a 
static charge.  A non-inductive resistor with a value between 5k and 50k 
will do the job.  If you use an antenna switch, that is a good place to 
add those resistors.  If you have no other choice, mount the resistor in 
a PL-259 body and put it on one side of a TEE adapter - the rig goes on 
one other side and the last side goes to the antenna.
