Cable routing was planned somewhat in advance. I
wanted to use as much of the pervious coax as possible. I manufactured some
metal brackets to hold the SO Coax splices to the tower legs. Made from 18g
Mild Steel and painted with Rustoleum Professional gray paint. An unpainted
patch was left on the back side for grounding.
Here is the final shot of
the entry plate:
You should note the bright copper patch from where the lightning protector
bracket formerly was bolted. I used the
Georgia Copper Connection Grease
(copper based) and this is the result 7 years later.

Given my penchant for good connections, despite living in sunny Arizona I
crimped the pairs of leads and then soldered them...
I borrowed my neighbor's Bosch hammer drill and
drilled three 5/8" holes through the slab. Rented a small demolition
hammer from Home Despot and my friend Manuel and I pounded in the 8' ground
rods. We tied a rope to the handle of the hammer and I went up on the
roof and hauled it up high enough for Manuel to get the hammer onto the rod.
I switched it on and the two of us guided and watched as it put the rod into
the ground. As could be expected I spent more time driving over and
back than I did driving the rods...
With the rods in place I stripped the paint from
the tower legs in three places and attached the brass grounding clamps to
the legs, lubing them up with the
Georgia Copper Connection Grease.
A piece of #2 THNN (Home Despot didn't have bare) was run from each of the
clamps to the rods and secured with a brass acorn clamp. Copper grease
was used on these connections as well.

seal around the rod so water does not seep in and combine with our saline
soil and corrode the ground rod.
