Midland MXTA12 Antenna Mag Mount vs Midland MXTA27 Universal Lip Mount

Both are Midland NMO mounts with 20 ft of RG58U cable and a UHF/PL259 radio connector, so signal loss and radio compatibility are effectively the same. The MXTA12 is a magnetic mount: it goes on and comes off in seconds and suits a temporary setup or a second vehicle, but it needs a steel surface and can shift or scratch paint at speed. The MXTA27 is a lip mount that clamps onto a trunk or hood edge with a set screw, so it stays put on rough roads and thin panels, but install takes tools and it leaves a permanent bracket. Owners of both report the cable and connector hold up well; the mount is the deciding factor.

• Choose the Midland MXTA12 if you want a mount you can move between vehicles or remove when not in use, and your roof or trunk lid is steel.
• Choose the Midland MXTA27 if you want a fixed mount that clamps to a hood or trunk edge and stays put on rough roads.
