NOTE:
The RT97P 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.

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.

With the package size:310×283×170mm. Weight less than 3kgs. Very small and easy to carry, you can use it outdoor.

Built into a cable TV amplifier box, the RT97P is rugged and water-resistant. Two power adapters come with the repeater, a 12V/24V cigarette lighter plug, and an AC adapter.

RT97P Can be powered by DC12V~24V power, car power and solar battery.

Both digital and analog model workable. You can use it to expand the communication range of not only digital radio, but also analog radio.
