So, my tower and antennas with their pointy elements at 55+
feet are more likely than my steel house to generate streamers
and get hit -- just no guarantees!

This discussion did draw me to look more closely at the Web
site picture of the ridge on my house and to think about some
raw/rough edges that may need to be rounded and/or closed.

Much as I hate to say it my tower and antennas may become
sacrificial elements in the defense of the house!

Hmmmmm.
