Sorry for this not being entirely topband-related, but I'm hoping some people here have tried this. I have a beam on a rotor than has lmr400 feeding it now. The cable has been damaged by critters tha

FSJ Heliax...or superflex as it's known in the industry is not rated for outdoor use. The outer jacket is so thin it metal fatigues easily. It's great for low loss jumpers indoors but I would never u
More of a topic for a VHF/UHF forum where the question comes up often.. I use that coax on the mast and to power dividers and out to individual yagis but it certainly is not meant to survive long aro
I turn 1/2" Cellflex cable which is similar to FSJ4 for more then 30 years and never had a problem. On one tower I turn a bunch of 5 cables at once. And yes, never damage by critters since using that
What is this antenna, tower, rotator, and cable configuration? Im also using 5 cables and around a Tailtwister rotator. Carl KM1H I turn 1/2" Cellflex cable which is similar to FSJ4 for more then 30
One option is to do what remote ENG trucks do and make at least a 540 deg or 720 deg (1.5 or 2.0 or more) loops rather than a 180 or 360. This will reduce some of the flexing action as it is more lik
That's what I was thinking all along. If you put enough large loops in it, you could even get away with using 3/4" aluminum hardline. :-) Of course, that doesn't mean it should be done. 73, Mike www.
I have used Andrew FSJ4 cables for years as rotor loops. Andrew does not recommend it outdoors, but I have come up with a good technique for its use. When you put the connectors on each end, be sure
Rotator is home brew with a slew drive of 76cm diameter and turns from north +/- 270°, tower is free standing and face width is 50cm at the top section. The 5 Cellflex cables are tied together with t
