Product Description


PufangTech`s UHF Radio Modem operates in 440-480MHz frequency band 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. These UHF radio modems work in transparent transmission, and they can ensure compatibility to most user systems and protocols. These UHF radio modems are perfect for SCADA, Remote control and telemetry for utility distributions (water, electricity, oil & gas).
