First, Season's greetings to you and congratulations on the new location and 
Second...Pretty much what Joe said<:-))
Start with a good ground system and go from there.
My trap tribander is just a relatively inexpensive and used TH-5 and it's 
still working.
I've said before, my tower and antennas gets hit an average of 3 (verified) 
times a season although it was
five times this past season. Since finishing up the ground system I've had 
no problems. Still, after all those hits the next one could be a super 
strike and fry the whole place.
