If you are operating with long cable runs from the bottom of the downconverter to the rear panel of the
PRORXD, it will be necessary to select a high gain version of the downconverter to deal with the RF losses in
the longer cable. Some downconverters are switchable between high and low gain.
Step 2: Attach the Antennas to the Downconverters
1.
Connect each antenna directly to the TNC Receptacle on the top panel of each downconverter.
2.
Do not tighten the antenna too much – tighten with your hand.
Step 3: Set Antenna Polarization
1.
COFDM links are very robust and are tolerant to changes in antenna location, but, it is important to try
and keep the antennas in the same plane if possible.
2.
The antennas used with the COFDM links are usually linearly polarized.
Step 4: Attach IF Cable to the Downconverter
1.
Connect the TNC plug on the IF Cable to the TNC Receptacle on the bottom panel of each
downconverter.
2.
Do not tighten the TNC connector too much – tighten with your hand.
Step 5: Attach IF Cable to the PRORXD
1.
Connect the BNC plug on the IF Cable to the BNC Receptacle on the rear panel of the PRORXD. They are
marked IF1 to IF8.
