Setting up your PRORXD
4.1
Planning the Hardware Installation
There are some general considerations for the installation of any electronics device or system. Not all of
these may apply to your installation but are worth noting:
Space – leave enough room to allow for cable bending and servicing
Proximity to other devices (for example, source equipment)
Length of cable runs – try to keep cables short
Environmental conditions (temperature, humidity, etc.)
Access for service repair
Compliance with local regulations
4.2
Connecting the Antennas
This topic describes connecting systems designed mainly for transporting the RF signals. Of all the
variables affecting single-channel radio communications, the one cause that an operator has the most
control with is the antenna. With the right antenna, an operator can change a marginal net into a reliable
net.
There are eight antenna interfaces located on the rear panel of the PRORXD-8-2RU receiver for example.
The PRORXD-2-1RU uses two.
Note: If you have four-way diversity PRORXD then you must connect four antennas to get best performance
from the four-way diversity receiver system.
If you have six-way diversity PRORXD then you must connect six antennas to get best performance from the
six-way diversity receiver system.
If you have eight-way diversity PRORXD then you must connect eight antennas to get best performance from
the eight-way diversity receiver system.
Before you Start
This is necessary:
2, 4, 6 or 8 downconverters that align with the frequency range you wish to receive.
2, 4, 6 or 8 antennas that align with the frequency range of your downconverters.
CAUTION: Do not turn the barrel of the downconverter when attaching antennas or IF cables. Too much
twisting force will damage the inner pin.
CAUTION: Do not install the Downconverter upside down. Power from the IF cable will damage components
in the downconverter.
Step 1: Select your Downconverters
All PRORXD receivers operate with downconverters to lower the frequency from microwave (L, S and C-Band)
to an Intermediate Frequency (IF) between 51 and 858MHz that the on-board tuners in the receivers can
operate with.
It is important to select the correct downconverter for the microwave transmission frequency you are
planning to receive. Downconverters have a label to help you select the correct unit.
