One of the most popular ways to increase the GMRS radio range is to use a GMRS repeater. This guide will tell you more about GMRS repeaters and help you to maximize the communication range.
How GMRS Repeaters Extend Range?
A repeater is a device that receives and retransmits a signal in order to extend the range of the radio. If you are in an area where there is an available repeater, you can use it to extend the range of your GMRS radio, such as Retevis New Arrival NR30. Enter GMRS repeaters, which act sort of like cell towers or relay stations to pick up our signal and send it out farther than what was ordinarily possible.
How Do I Set Up My Own Repeater?
You can purchase a ready-to-go GMRS repeater setup using a Retevis RT97S portable repeater that plugs into your vehicle’s cigarette lighter. Retevis RT97S is a GMRS portable repeater, which has 8 GMRS Repeater Channels. 462.550 – 462.725 MHz (TX), 467.550 – 467.725 MHz (RX). It can powered by solar battery, and its built-in sound card can be connect to Raspberry Pi.
Before just jumping in and setting up a repeater, make sure you are aware of other repeater systems operating in the vicinity, what tones or DCS codes they use and be sure to follow FCC guidance on emissions, antenna height, etc.
High Gain Antenna For Longer Range
For places where need a big more range from our truck’s mobile GMRS radio, you can bring along a small directional antenna, called a Yagi. These small directional antennas are compact enough to take along and set up at base camp. We can set this directional antenna up on a long pole at our campsite. For example , Retevis AY04 Yagi antenna has 9.5dBi-11.5dBi gain, which can greatly boost handheld radio’s ERP.
