I have an APX 7500 (VHF, UHF R2) I am looking to get installed. Before I do, I have a few questions about antenna spacing on a 2011 Ford Explorer. I will be using two antennas for the different bands on the radio, one is a quarter wave VHF whip from Laird, and the other one is a quarter wave UHF whip from Laird. My question what is the appropriate distance between the two antennas. I have read other threads on this topic and they seem to mention 18 inches as a good distance between antennas. However, currently I have one NMO mount that is used for a temporary setup that I will use for the APX radio which is center mounted. For the other mount following the 18 inch rule, it would end up being mounted on the side of the roof which could cause some issues with polarization and not so great reception.
I have attached two pictures of where I might want to mount the second antenna which is a VHF antenna.
This picture shows the VHF antenna mounted in the middle of the car
