DanThe best GMRS Repeater to expand my handheld radiosReviewed on Jul 18,2023Presently I am getting 16 miles of coverage in a mountainous area. This summer I will place the unit at about 7000 feet after the snow recedes and should get 100 miles coverage. The best GMRS Repeater to expand my handheld radiosBoyd B.Portable RepeaterReviewed on Nov 22,2022This mobile and durable repeater works well for the GMRS operator looking for versatility. This repeater increased handheld transceiver range by several miles with even just a small mag-mount antenna. The repeater is even reprogramable. Highly recommend.
