3 INSTALLING AND CONNECTING THE OUTDOOR UNIT
The wireless frequency band determines the type of the combiner and antenna. The WMTS
operates in the 2750 band.
3.1 RF Connection
3.1.1 Downstream
Connect the WMTS upstream card connector (F-type) to the upconverter IF In connector,
through 10 dB attenuator.
Note: The nominal output level of the downstream IF OUT signal is 43 dB, and the
typical IF output level to the upconverter is 33 dMmV. If higher input level is required,
adjust the input level by changing the attenuator or by adding an amplifier between the
WMTS IF output and the IF input of the transceiver.
3.1.2 Upstream
Connect the IF output of the downconverter to the IF IN (F-type) connector of the
upconverter/card. Use a splitter if one down converter drives more than one upconverter/card.
