Attaching coax to insulated backstay
Exposed HF feedline connections:
For your consideration:
1. Use an anti-oxidant compound* on the cable, stay, and lug, then seal overall.
* Ideal “No-Alox”, Burndy “Penetrox”, GB “Ox-Guard”, etc.
2. Use a Tin-Plated Copper alloy “Split-Bolt” Connector, such as: Burndy type “KSU” c/w “SU” Cover or equal. See pages 4 & 5 at:
3. Separate the feedline from the stay (inductance in parallel conductors). Cut 2" pieces of small diameter rigid plastic tubing/pipe with a larger diameter drill bit. This leaves the cut ends with a curved concave profile (that matches the stay & cable diameters). Insert a tie-wrap through the tube, around the stay, back through the tube, and around the cable & draw tight. You have a 2" stand-off”.
I''ve never had any customer complaints (/w above), but I''m not a HAM, so my experience is second hand.
