SD-671DE V2 VHF 150-174 MHz

The Maxon SD-671DE DMR Digital Radio Series of radios are durable, reliable and designed to meet the needs for a variety of wireless applications. The included Digital Vocoder (AMBE with AMBE++ Voice Compression Algorithm) allows 9600 Baud Rate capability adding even more diversity to this cost effective radio.

The modules incorporate the most requested mechanical footprint and BNC antenna connection. Transmit power settings from one to five watts provide the power needed on any job and the LED indicator gives instant on-sight status of the radios operation. Combine that with low current drain and fast transmitter/receiver attack times for operation in the harshest of system demands. The die cast aluminum cabinet/lid provides resistance to RF interference; and gives exceptional environmental durability in the most extreme conditions.

Whether implementing a new system or installing into an existing system, the Maxon family of data telemetery radios have been the choice of OEM and end-users worldwide for over 25 years.

Maxon's 3 year warranty and FCC Certification logo certifies that the electromagnetic interference, safety, manufacture and other quality parameters have been met by the Maxon SD-671D V2This diagram shows a typical water control system using data radios like the Maxon SD-671D V2
