[TowerTalk] Outdoor HV Cables

[K9MA]

Just in case this is of use to others:

I needed to make some jumpers to go from the bottom end of my shunt feed 
gamma matches to the tuner. There's about 5 kV on the 80 meter one, so I 
wanted high voltage insulation so someone doesn't get an RF burn. (The 
rest of the first 10 feet of the gamma match is in PVC conduit.) I've 
used RG-8 center conductors before, but the insulation doesn't hold up 
well in the sun. I didn't want to leave the shield on, as it adds too 
much capacitance. I had some new RG-213 from DXE, and found that I could 
slide the outer jacket off of a 3 foot length, remove the shield, and 
slide the jacket back on.  I just had to strip an inch at one end, clamp 
it in a vice, and pull. Instant UV resistant, low capacitance, HV cable. 
This may not work on all RG-8/213 type cables.
