User Manual

Description of the radio telemetry equipment
l0 W RF output~ power (rain);
One REM in each RF cell (1 retrieve frequency);
Up to six REMs can be used on one antenna;
Maximum number of REMs in a network: 16;
Typical range: 16 to 24 km (10 to 15 miles).
The REM has a built-in signal strength meter used to monitor the RF Spectrum on
the HCI workstation, and an output for connection to an external spectrum analyzer
with a finer resolution. The signal available on the Spectrum Analyzer output is
picked up at the antenna with a 20 dB gain.
Preamplifier
If a preamplifier is used between the antenna and the Antenna connector on a REM,
then the REM Layout Setup on the HCI workstation must let the REM supply a 12
V DC voltage to the preamplifier over the antenna downlead in receive mode.
If any filter is used that does not relay DC voltage, then a DC Block must be used to
supply power to the preamplifier.
