About 20 years ago I decided to do something about lightning protection.
My tower is 80 feet of Rohn 45G, with a 5el Telrex monoband 20 meter yagi at 82
feet.
Hygain 153BAS at 90 feet and Hygain 103BAS at 100 feet. I have a homemade
antenna
switch box near the top.
I shunt feed the tower with an Omega Match for 160. The shunt rod is 1/2inch
EMT
conduit.
I use vacuum variables in the Omega match.
At 65 feet I have a Diamond X200 for 2meter/440mhz. all cables come to the base
and go underground
to a steel box at the entry to the house. The HF antennas are fed with RG-17
and
go through an ICE
308 15kw coax arrestor. The X200 is fed with RG213 through a PolyPhaser
arrestor. The control wires
all go through PolyPhaser arrestors. I made LC to UHF adapters.
My tower is the tallest thing for several miles. The tower is guyed with 6700lb
Phillystrand.
So far so good.
