|
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.
