The GMRS-POINT5 optimizes your GMRS radio by delivering the best signal performance throughout the programmed channels. Measuring a total of only 14.5″, the GMRS-POINT5 antenna packs big performance in a small size. Molded high heat ABS mounting base features silver soldered connections, gold plated push pin contacts and o-ring. For optimal performance, we recommend a ground plane surface mounting such as a metal roof, which aids in signal performance. Please refer to our Rugged Radios’ Tech Installation Guide for proper antenna placement, preparing the surface area, and installation.
