I have used FSJ4-50b flexible hardline for rotor loops for years… never had a problem.
Proper cable support on each end of the loop is a must.

Hello all, for what it’s worth, I use LMR600DB and LMR 400DB WITH 3 loops . At maximum
rotation the minimum Bend radius is 2x the manufacturers recommendations. In 14 years with
the same cables.,,, no problems. Never use one loop.,. Always 2-3 full turns... the helix
created then compresses or opens!

Thanks all for answering to my question regarding the use of low loss coaxial cables in
combination with an antenna rotator.
Ecoflex 15 should be avoided! several people reporting cracks in the copperfoil causing
Hyperflex 13 and Superflex 13 (M&P) also suffer these problems, several people
reporting this as well.
The standard 10mm coaxial cable seems better, not seen any direct report of foil
SCF12-50 still seems to be the best solution, but it is recomended to use a double loop
which is large enough.
Also LMR600-UF seems suitable, but I wonder if this cable is not suffering the same
problems as Ecoflex 15/13mm cable as discribed above.
Maybe LMR600-UF has double breading?
