The Retevis RT97L 25W GMRS Repeater Kit and HA1G radios form a robust communication system tailored for high-stakes environments. The RT97L’s industrial-grade power and weather resistance eliminate signal gaps, while HA1G’s long-range versatility and emergency features ensure rapid response. Together, they excel in scenarios demanding reliability, mobility, and adaptability—from coordinating bike races across rugged trails to executing life-saving mountain rescues.
Right for industrial, or agricultural settings, it minimizes signal dead zones and ensures a stable connection with your Raspberry Pi.
Portable with one hand, it adapts to dynamic needs, allowing for free and agile movement as usage scenarios change.
Equipped with an LCD screen design, ensuring that critical information is at a glance.
HA1G GMRS radio includes 30 GMRS channels, of which 8 repeater channels can be connected to a repeater to extend the communication distance. An additional 220 programmable channels allow you to program multiple repeater channels for ease of use and extended range.
2. IP67 WaterproofThe HA1G GMRS two-way radio has an IP67 waterproof rating to withstand harsh rain conditions and can be used outdoors in rainy weather.
3. Dual StandbyHA1G GMRS portable radio can effectively stand by on two channels at the same time, so you will not miss important information.
4. Long Battery LifeEquipped with a 2800mAh large-capacity battery, the Ailunce HA1G GMRS walkie-talkie is efficient enough to support all-day outdoor activities without frequent charging.
5. NOAA Weather AlertsThe dual-watch function allows you to monitor NOAA while communicating with your partner. NOAA weather channel scans and locks the strongest weather channel to remind you of severe weather updates.
6. Support Type-C ChargingThe HA1G GMRS two-way radio supports Type-C charging and desktop charging. It is convenient to recharge the radio through a power bank, a vehicle, etc.
7. 1.77-inch Color DisplayAilunce HA1G GMRS handheld two-way radio features a 1.77-inch color screen, which provides convenience for checking the current working channel and battery condition during outdoor activities.
