[Towertalk] Rotor Loops

[n8kwx2@attbi.com (Marc Holdwick)]

I just checked the archives and didn't see anything that addresses my
question:


What is the proper way to do a rotor loop?

It seems that the usual way is to fasten the coax parallel to the mast just
above the top of the tower do a U shaped loop (in a vertical plane) and then
refasten it parallel to the tower legs.

I was playing around with this and it seems that it transfers the rotation
of the mast into torsion of the coax.  Is torsion "good" for coax?  (I'm
planning on using Cable X-Perts' CXP-1318FX [LMR-400UF equivalent]).

Another method that I can envision is to have the coax come off the mast and
tower PARALLEL to the horizon and do the loop in the horizontal plane.  Now
the coax will coil and uncoil versus twisting.

Would this be better for the coaxial cable in the long-term?

Any comments?


Thanks & 73,
