Hello all and season's greetings...

I am moving to the highest point in the county, a ridge line 1800ft up from 
the surrounding valleys. I intend to install a high tower [60-100ft] with a 
40m yagi over a tribander and a wire antenna system for the low bands. My 
house will be more or less under the antenna system. My kids live across 
the road, and they receive up to five direct lightning hits per month 
during the summer. With the tower I can expect to become the "local 
lightning rod" and will probably receive at least that number of hits and 
probably more. This raises questions concerning antenna selection and site 

Antenna: assuming the antenna/tower will be hit frequently, should I avoid 
trap antennas and those with embedded electronics [eg SteppIR], or should 
such antennas be okay for these conditions? Are there any antennas that are 
knows for their lightning strike endurance?

Protection: allowing for all the lightning arresters, spark gaps, drains, 
shunts, grounds, etc, all on feed lines and control cables, all entering 
the house, all connected to the radio equipment, what's the general wisdom 
on what I should install/do to keep things from being fried on a regular basis?

Thanks much.
