Batboard

i'm going to be doing a multi-radio install and i was wondering if it's taboo to run antenna wires right next to each other up the a- or b-pillar. all the antennas need to be on the roof (spaced as best as possible). the radios in question are as follows:

cdm1250, vhf-hi
cdm1250, uhf-t
icom ic208h, dual-band 2M & 440
cobra 75wxst, CB
uniden scanner bc796d, (obviously all bands)

just wanted to know if there is any antenna wiring i should keep away from the rest? i'm thinking maybe keep the 2M ham(~146Mhz) away from the vhf-hi and keep the scanner away from everything? is that ok or not even necessary?

thanks

Depends, you have to consider transmit power, coax quality, etc.

If you use a good quality coax with tight shielding you could run them all up the same spot without a problem. The equipment is also a matter though. For example, a scanner with a wide front end won't have the rejection to strong nearby signals that one of your other rigs might have.

The worst i can see happening is the scanner receiving interference when transmitting on one of the other radios.

I agree with the previous post... In my past expirence I ran a bundle of coax down the C post of my previous truck. This was for multiple TX radios and a couple RX scanners. I never had any problems with interference on the scanners when transmitting on the radios. So you should be good to go!

ok thanks guys. i'm gonna bundle em all up and hopefully no problems. thanks.

Another thing... as long as your SWR is good you shouldn't have any problems. You'll want to keep all that stray RF off the coax shield!

yeah, that's another thing... i'm also in the market for a good swr meter. i saw the other thread about the telewave 44a. i might take the plunge.

Just did an install tonight on an Explorer with 3 Antenex NMO's using Teflex coax, running in a bundle down the C pillar. Radios are 110w VHF/UHF X9000's and a 35w 800 Spectra....no issues.
