On my LM-70 I use three cables up..Co-ax...Rotor control cable...Quad band Switching cable...these cables cut to length are taped together very carefully in a straight triangle with no crossovers....they are feed into a length of "Braided 1 Inch Shield".....The Braided Shield is then pulled-stretched and grabs and locks onto the cable the top of the tower the cable stand off arm is re-enforced, and at the point just below the cable turn toward the tower a "Large Cable Grip" is installed, with about an 8 inch grip/grab sleeve....the grip is made so the outside woven braid shield is grabbed and carries most of the cable weight. This way the vertical weight is being shared by the ..Braided sleeve and the three cables equally.... Because it is a very neat install...when the tower is retracted the cable coils up perfectly at the base...

Has anyone found an improved method for running coax down crank-up towers ?

I have seen the fixed arms where the coax "accordions" as the tower comes down. I have been told that even with the tower fully extended the coax whips around in the wind

I have seen the "loop" or ring standoffs where the coax "threads the needle" as the tower comes down and the coax piles up on the ground or in a container. I would think there is a lot of stress on the cable having a single attachment point at the top of the tower. Also some logistic problems with the coax piling up.

Any improved ideas ?
