The Midland MXAT03 Canyon Edge is a 28-inch, 3 dB fiberglass GMRS antenna on a stainless-steel spring base. It runs the 462–468 MHz GMRS band and pairs with Midland MXT-series MicroMobile radios. The cable assembly is 19.5 feet of coax that ends in a UHF male (PL-259) connector, so it routes from a front bull bar through the firewall to a cab-mounted radio without splicing.
The 3 dB rating is the point, not a compromise. Lower gain radiates a taller signal pattern; higher gain flattens that pattern to push range across open ground. On flat desert two-lane, a high-gain whip wins. In hills, dense timber, and canyon country, that flat beam shoots over ridgelines and drops the other rig. The 3 dB pattern reaches up and over the terrain, so comms hold when the trail dips into a valley or threads through trees. Midland recommends 3–6 dB for most overland use; 3 dB is the obstructed-terrain end of that range.
The whip is fiberglass and the base is a stainless spring, so a branch strike flexes it and lets it snap back instead of snapping off. The kit includes the antenna, spring base, and 19.5 ft cable. It needs a 0.5-inch mounting hole; the bull-bar mount is sold separately.
