The bracket replaces the metal part of the original design. The metal hardware of the original design is replaced by:
- 1 Flange type 2x2 M4 hole UHF plug
- 1 M10 Nut
- 2 M10 elongation nuts >= M10*30
- 1 M10 threaded rod 30mm (top)
- 1 M10 threaded rod 40mm (bottom)
- 2 additional M10 cable lugs for the ground connection at the bottom + wire
- 2 additional M4 cable lugs for the ground connection on the UHF Plug (the image shows the cable haphazardly clamped between washers. don't do that :D.
- X additional M10 cable lugs for the ground counterpoise. Instead of 8 wires per bundle I suggest 8 bundles of 3 -4 wires in each M10 cable lug.
See the picture for how it all fits together and what goes where. The Counterpoise lugs should be added between the short nut and the elongation nut at the bottom (now shown in picture)
The slot in the installation position of the UHF plug
