    I already have a roof mount cell phone antenna. I would like to add a roof mount CB antenna (no wires showing) but I did not want to create a problem with them being too close together. I will be running a fairly small antenna, and legal power on the CB. I don't need much range, just to talk to friends traveling with me.

    I don't see a problem with it. Serously, are you going to be keying up the CB when you're on the cell phone ?????

    I don't expect to use both at the same time other than the phone will be connected and turned on. I may try it with a magnetic mount before I start drilling holes. Thanks! /forums/images/graemlins/thumb.gif

    You'll be fine. There is a huge frequency difference between CB's and cell phones.

    That has more to do with the wiring than the antenna's. That used to happen to me when I put an external amp on the radio. I ended up putting filters on everything and running the antenna wire different and it all cleared up.

    Yep, that's just RF interference. Get you a good noise filter on your AM/FM radio to help with that. Of course if your pushing a lot of power then it may not help much. I used to get some cell phones way back when they were in the 800 mhz range before the new digital ones. If your running a 102" steel whip they like to leak RF pretty bad.
