cell phone antenna & c b antenna

[Old Man]

I have a cell phone antenna located on the rear glass behind the driver. I plan to mount the CB antenna on the side of the tool box. Will there be any problems with the two antennas. Where are you guys coming in the cab with the coax cable. I have all my wires and the boost line coming in at the big grommet with the big wire harness (on firewall) and don't want to use this locating. Afraid I'll mess something up. Drill a hole in the firewall or come thru the floor?. Thanks for you patience. Old Man 2001 3500 ETH/DEE (sorry for the long post) Happy Holidays to all.

Nada on the interference between the 2 antennas. My coax was brought in thru the floor & grometted. If you go thru the firewall, you may find enough room thru an existing gromet. Some are nice & wide. If you can find one with a thin rubber area, you can slit it with a knife blade & shove the coax thru.

the main grommet for the wiring has a wide outer area, just poke a screwdriver through and follow that with a wire hooked on the cable and pull through. the rubber is thin and easily pushed through. there is enough room to not worry about messing up wires.
