[TowerTalk] Orion 2800 Rotator Cable Replacement

[Wayne Kline]

I have found that  exposed  THHN will loose it’s clear layer after a few years exposed, BUT the vinyl coating stayed in tact for some time.
At my Old QTH my PropPitch rotors were feed with THHN I then and upgraded  #10 UF wire and am using it at this QTH for 30 years with no problems,
I transition form the UF to flexible cable from a WX proof junction box

YMMV

That's surprising.  I found that THHN loses its clear outer layer
after only a few years in the sun, let alone decades.
