The lowest price I have been able to find for these kits is about $34 each. DX
Engineering wants $42 and change. Andrew makes grounding kits that are around
$10 at TESSCO, but you have to engineer your own dissimilar metals protection -
I have been very happy with stainless steel shims between copper wire and the
galvanized surfaces of my tower.
Perhaps there's something wrong with this idea, but why not fabricate a bracket
to bolt to your tower top and bottom to mount the required number of UHF
barrels, providing a solid low-inductance ground path for the cable shields?
Your rotator loops should probably be replaceable anyway, and well taped
connectors should not pose a reliability problem.
