[TowerTalk] US Tower TX489MDPL Coax Sidearm Question

[force12@interserv.com]

The loops of coax always looked like a good idea, but I have gone away from 
it. During windy conditions, the loops hung up too many times.

The present solution is to use one at the top, with a curved support for all 
the coax. This can be a section of conduit or PVC. The main concern is to 
be sure the weight of the coax/cable bundle is not going to compress the 
coax. I also use a strain relief, so the coax and cable weight is not on the 
curve, but held below the lower end of the curve. The coax/cable is taped 
every 18" with 33+ tape (no stretch on the lat wrap). At my place, I do not 
use any lower arms at all, because I use the coax/cable bundle to also haul 
up the noise receiving antenna for an ANC-4 box. At other locations, I have 
used all the arms with the coax/cable bundle sliding through the ring. The 
rings are closed into a circle and then a combination of tape and loom 
mate5rial (spiral wrap) is placed around the ring so the coax/cable will 
slide easily and not hang up. If you do not want the coax/cable to pile on 
the ground, a large salmon net can be attached to a tower side to catch all 
of it. It doesn't tangle in either case.

Maybe this will add another option to the pot.



Have a good day and 73,
