  • Description
When range matters, this is the kit to choose. Using the same proven mount that fits 2007โ€“2018 Silverado/Sierra trucks, the 2019 HD Classic, and GM SUVs and Avalanche models, this setup pairs a strong fender mount with a purpose-built high-gain GMRS antenna.

This antenna is designed to push your signal fartherโ€”ideal for group trail rides, farm operations, search-and-rescue teams, and anyone who relies on clear, extended-distance GMRS communication. The mountโ€™s reinforced structure handles the added leverage of a taller antenna while keeping it stable at highway speeds. With the included coax and stud, this complete GMRS antenna system installs cleanly, performs exceptionally, and transforms your truck or SUV into a capable long-range communication platform.

MXTA26
This 32-inch whip antenna quadruples signal output. When maximum range is your goal, the MXTA26 6dB gain whip antenna is the perfect choice. Great for off-roaders, farmers, and more, this long-range antenna is designed with a spring at the base and a coil at the center. The spring allows for extra flexibility to prevent damage from light, incidental contact when youโ€™re traveling off the beaten path.
