[TowerTalk] ground plates (was DXE Patents)

[James C. Hall, MD]

Interesting - what about using copper split bolts on that ring of 1-0 copper
? No soldering. Multiple radials under one bolt, too.

Strain relief. If the radials are firmly attached to the solder lugs then
there is little likelihood that they will separate from the plate if pulled
on, kicked, etc. My radials are up about 10 feet in the air
- I have them not just crimped, but the wires go through the crimp
connection and form a loop  around the screw head before passing back
through the crimp. They simply do not pull out.

If the bus bars are used, the wires tend to pull out rather easily, no
matter how tight the screw is. I also note that the bus bars are generally
aluminum, so we still have the problem with copper (wires) and aluminum
contacts...
