The Midland MXAT04 is a 47.5-inch, 6.6 dB heavy-duty fiberglass bullbar antenna for GMRS radios. It tunes the 462-468 MHz GMRS band and mounts through a standard 1/2-inch hole. The fiberglass whip is built for trail abuse and is water resistant for full-time outdoor mounting.
The 6.6 dB gain is the reason to pick this one. A 3 dB stubby keeps a low profile but throws signal in a wide, short pattern. A full long-range whip reaches farther but stands tall enough to catch every branch. The 6.6 dB sits between them: it flattens the signal toward the horizon for more open-ground reach without going full mast height. On wide, lightly obstructed terrain like fire roads and open desert, that extra gain is real distance.
This is the antenna only. The heavy-duty spring base and the 19.5-foot coax come in the separate value-pack SKU. Like every mobile GMRS antenna, it needs a ground plane to perform: roughly 12 inches of steel or aluminum across, and it does not have to be a continuous surface. Backed by a 1-year warranty.
