Installing the hub
This section provides instructions on how to install the hub on a cable strand with AC
power provided over the coaxial cable. The hub can also be installed on a rooftop, mast
or tower using the AX1655-SMA pole mount adaptor kit. It can be powered using power
over Ethernet per the wiring diagram provided in the previous section.
Aligning the hub
Attach the bracket to the messenger strand with the two hanger bolts. Position the hub’s
antenna (located behind the radome) to the azimuth and elevation determined by the
wireless link planning. The azimuth position is adjusted by placing bolt A in the
appropriate location on the azimuth alignment bracket and the elevation is adjusted by
loosening bolts B and rotating the hub face up or down and tightening bolts B at both
ends.
Connecting the hub
 Install a CATV power passing/extracting tap suitable for your plant and
the hub powering requirements. The hub draws 24 watts maximum and
can accept 50 Vac and 110 Vac.
 Verify that the input downstream RF signal level is between 0 dBmV and
+30 dBmV.
 Verify that the modulation error ratio (MER) of the downstream signal is a
minimum MER of 35 dB for 256 QAM and 31 dB for 64 QAM
operations.
 Connect the hub to the cable plant using a setup suitable for the cable plant
and hub powering requirements.
