My intent is to gently tie wrap the 3 cables together using UV-rated outdoor ties, then leave the appropriate loops and slack so I can raise and lower the tower. The Orion 2800 rotor is already mounted, tested with a mast that’s ready to receive the antenna.

I have all my cables (2 x coax + rotator + SteppIR) taped together with 
electrical tape. Since they run through my crank-up's coax standoffs, 
cable ties would catch too easily.

The electrical tape (one of the 3M varieties, but I don't recall which) 
has been there a few years, but I guess I have to replace it soon.
