RT97S Customizable Full Duplex Portable Repeater
The RT97S repeater is ideal for solar-powered repeater sites where low power and a small footprint are required. At such a small portable size, this repeater is perfect for farming, camping trips or emergency preparedness.
Customizable Frequency
TX frequency and RX frequency can be customized between UHF (400-470MHZ) or VHF(136-174MHZ). If you need to customize the repeater, please note the following information when placing the order: RX frequency, TX frequency, Offset (Offset ≥5MHz and ≤12MHz) and Charger type. 
Car Charger
Built into a cable TV amplifier box, the RT97S is rugged and water-resistant. Two power adapters come with the repeater, a 12V/24V cigarette lighter plug, and an AC adapter.
Multi Charging Methods
RT97S Can be powered by DC12V~24V power, car power and solar battery.
