Rugged VHF/UHF Radio Receiver

 

Model AR-9










 

The VLF/eentec AR-9 is a reliable, rugged, low power, field telemetry receiver. The design features frequency synthesized operation over a 10Mhz range. Frequency band within a specific 10Mhz range must be specified at time of order. Minor frequency changes less than 100Khz, can be made by the user by changing dipswitch positions.

The AR-9 is completely compatible with Monitron radios and can be used as direct replacements in existing telemetry networks. In new networks, the unit receives data transmitted from the AT-9 field telemetry transmitter.

The unit is housed in an anodized aluminum case. It has a standard pin-out twist lock connector for power and audio input. The standard input connector is a “N” style with UHF or BNC optional. All connectors are wired to Monitron standard.

Options and accessories include VHF frequency band, rack mounting packaging, radio rack, lightning protection and Yagi antennas.
