[TowerTalk] Can 1/4" or 3/8" Andrew SUPERFLEX be used for a Rotor loop?

I can see Ultraflex cables from 0.2" up to half inch;

Superflex cable is called from the hard coax point of view, but this Superflex has solid copper core. I think is not a good idea to keep a solid copper core turning and un-turning it that ofthen, will break.

Best recommendation would be to use a really flex cable, but you can get better cables than RG8/RG213.

Have you seen M&P cables?

Or Ecoflex?

Dick,

I purchased some 3/8 Superflex with the same idea.  I was talked out of the idea, and now plan to run LFD4-50A up to the rotor, and DX Engineering 213 to the antenna.  If it is good enough for K3LR, it is good enough for me!

Hi Guys,

I'm wondering if anyone has successfully used 1/4" or 3/8" Andrew SUPERFLEX all the way from your shack to the antenna, including forming the rotor loop?  I'd like to use a one piece Superflex cable from the shack to the my VHF antenna including having it form the rotor loop.  I'd locate a large rotor loop in the middle of the rotor rotation range so the most the Superflex would ever have to move is 180 degrees.
Please advise if this can be done with SuperFlex?
Thanks & 73,
Dick- K9OM
