I was wondering if running rg-213 side by side tied together with ties for long lengths could cause any negative affect in signals coming in or being transmitted? This may sound like a silly question, but I do know that ckokes can be made from coax and therefore positioning can in some cases create differences in performance. What do you think? Should the coax have a few inches between them or is it ok to run the two coaxes touching together tied with ties for the length of the run?

You shouldn't have any problems if the runs are the same length and are commonly grounded at both ends.

I know of a ham that has 6 runs of thick double screened coax running from the front of his house to a gang of beams and verticals at the bottom of the garden. A length of over 60 feet.

Heck, done all the time at commerical sites. Ive run 20 or more bundles together without problems AS LONG AS the coax is all good grade with decent sheilds on them. Just don't try it with poorly sheilded cables though.

I have three Runs of RG 213 (Beams, Horz & Vert and Omni 305 coax) as well as Mini 8 for my 2 meter antenna and rotor cable, all tied together with UV Nylon wire tie's in a run of about 100' down tower thru 3" white PVC pipe into house.

And as soon as New Omni Antenna arrives I will add another run of RG213 to it.

No problem's so far.

I have the same problem...

I solved my problem by running some nylon rope between the shack and the antenna. I then loosly suspend the coax on the nylon rope using those black zip ties.

The rope takes most of the pressure off of the coax so that the coax is just hanging there held up by the rope. I have ran several lengths of coax on the same rope support without any ill effects.

Good Suggestion for coax I never thought of that trick before.

I use coated guy wire for the same thing attached to my tower on one end, and a fence post on the other before it comes into the shack.
