Product Description

Operating in 480-520MHz frequency band, GD480HH25 is an UHF ( Ultra High Frequency) radio modem with output power of 25 watts. The air data rate is 19200 bps in 25 kHz channel spacing and 9600 bps in 12.5 kHz channel spacing. These UHF radio modems work in transparent transmission, and they can ensure compatibility to most user systems and protocols. They are particularly suited for outdoor use under varying weather conditions and are perfect for SCADA, remote control and telemetry for utility distributions (water, electricity, oil & gas).
