Don't think you will have any problems keeping the cables together. I don't
think cable ties is that good idea as they may cut into the the cable jackets.
I use a combination of electric tape and REAL duct tape, the aluminum type
myself.
I don't know how important it is but I avoid using equal distance between the
places I tie the cables. Rumors have it that the small impression on the coax
will cause a reflection and if they are all at equidistant the reflexes can add
up a some frequencies to give a high SWR. Rumors or not, I have tie point at
random distances.

Subject: [TowerTalk] Running feed line and rotor cable together?
Greetings Fellow Towertalkians-
Just wondering if anyone has any recommendations regarding the routing of a
LMR400 UF coax feed line alongside a 4-conductor rotor control cable, and a
control cable for a soon-to-be-completed SteppIR DB-18 antenna. 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.
Anything else I should be mindful of? All cables are shielded and will be tied
to a common earth ground. I'll be feeding the antenna with 100 W max.
If not tied directly next to each other, what would be a good separation
distance for the coax and the other two?
Your collective wisdom is greatly appreciated by this relative newbie. :)
73,
-Paul, W2PIR
