Close up of mobile mount.

I had to use a slightly different mount than originally planed. The roof rack rails are a bit under 3 inches wide which required a special mount for it. Seems this is more common on newer vehicles, the wide roof rack rails.

The antenna mount itself used an "UHF" type socket, SO-239, since that matches the mobile antennas I already own. The lead in cable is 13.5 feet of really thin RG-316 coax. I needed to get some SMA to RG8X mini coax adapters to use the extension cable.

The RG8X mini coax adapters look like miniature RG-259 ones but the big difference is they are rated for a constant impedance of 50 ohms up to bit over 2GHz. The RG-259/SO-239 connectors are not recommended for use above 300MHz.
