Looking to pair a Midland MXT275 GMRS radio in a vehicle with a Browning BR-176-S antenna (pic attached). Having trouble researching NMO mag-mount antennas for this in terms of finding one with low loss. Have read these mounts can be very lossy. They all seem to use RG-58 cables and the cable lengths only vary by a few feet (don't want cut it shorter and install new connector). Anyone have strong feelings toward a particular NMO mag-mount (with cable) when it comes to loss considerations? Antenna note: I need a short antenna to get in my garage; want it on the roof of the bride's Forester. Considered a 6db lip-mounted 5/8 wave on the lower corner of the hatch near the rear bumper, but the cost goes up (as does gain) but I felt it might be less "omni-directional" if it were mounted there. Was looking at the Midland MXTA10 antenna but it's discontinued and not available in the more common places. Suspect the Browning might be a bit better quality but, right now, it's the only one I can find that's short enough for my considerations so I think I'm going with it. Anyway, I'm searching for an NMO mag-mount and would love to hear back if anyone has any knowlege about which models might have less loss. The radio is only 15W so I wanna retain as much power as I can.
