Kip, keep your fingers crossed and hope you don't get hit with a
positive strike.

9.5 out of 10 are negative.  Positives are in a completely different
league.  An order of magnitude more intense in voltage and current.
Broadcast heliax jumpers melted--all kinds of nasty and expensive
stuff.

Our club repeater antenna is high in the air. While I have not witnessed
a direct lightning strike, we can see the pit marks of many direct
lightning strikes on the antenna over the 15 years it has been in
operation.  The antenna and repeater are still in working order, and
still taking direct lightning strikes.
