Default Installing an NMO cb whip next to my Ham whip

Hi folks, I am going to be installing a Larsen CB whip on my roof, which already has a Larsen 2/70 mounted in the center. I was looking for suggestions on where to mount, considering the proximity of the existing antenna.

Should I mount it centered between the Ham antenna and the end of the roof? Or should I mount it closer to the rear of the roof, leaving more space between the antennas?

Thanks,
KJ6VWH

If it were mine, I'd put it close as possible to the 3rd brake light. Far enough away so that the vehicle's wiring isn't fouled. Or stick it on one rear corner.

I agree with Doc. Right in front of the third brake light.

I had 3 antennas inline like that in my caravan. Larsen 2/70, 2m 5/8 wave and a GPS puck.

Anywhere there was a light or panel I could pull to get roof access and not still through the headliner ;-)
