[TowerTalk] Rotor loop coax choices ?

[Mark Spencer]

Hi, I've typically used RG 214 for rotor loops with good success.  I've more or less run out of RG 214 and am wondering about the pros and cons of Belden 9913F7 (the newer style of 9913) and flexible lmr 400 style cable (the type with the stranded center conductor.)

I've had good results with 9913F7 in the past but have never used it for a loop around a rotor and it is now hard to obtain locally over the counter.

I picked up a short run of generic FLexible LMR 400 to try out but am not sure this is the correct choice.  I'll likely use it for patch cords.

The price for new RG 214 is causing me to look for alternatives and I used it in the past because I had it on hand and it seemed suited to this application.  

I have nagging doubts about using cables with a solid foil shield for a rotor loop.

I do like the idea of double shielded cables so RG213, RG 8 etc are off the table for now.

Any comments are welcome.   

Thanks
