SD-171 148-174 MHz 5/1 Watts
The Maxon SD-170E Series RF Data Link Telemetry Radio delivers reliable 2-way communication & remote control for a variety of application needs. Available as VHF (SD-171) or UHF (SD-174) with 1 or 5 Watts programmable output and 16 channels. The SD-170 Series provides reliable data or voice communication at all times. Crystal clear audio quality makes the SD-170 Series an ideal radio for golf course and emergency call boxes. When paired with the optional GMSK or FFSK modem board, the SD-170 Series transmits and receives data for wireless security systems, or it can be used in conjunction with police mobile data terminals for license tag checks. The optional GPS receiver turns the RF data radio into an Automatic Vehicle Location system for tracking fleet movement and communicating data directly to a computer.
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.
