Mounting the CMAP
To mount the CMAP assembly on a cable strand, you need to secure the cable clamps that
are attached to the strand interface bracket to the cable strand.
NOTE: The CMAP must be installed on a cable strand by a professional cable installer.
The CATV coaxial cable used in the actual field deployment must have 45 to 90 VAC power
multiplexed with the RF signal on the coaxial cable since Connector B is used for both
electrical power and the RF signal.
To mount the CMAP
1. Slightly loosen the square nuts that fasten the two cable clamps to the strand bracket,
enough for the strand support cable to fit into the cable clamps.
2. Place the cable clamps on the strand support cable.
3. Tighten the two square nuts to approximately 16 ft-lbs to secure the mounting.
4. Connect the CATV connector from the cable lines to Connector B on the CMAP. Select
a CATV power passing tap that will supply a signal level between -15 and +15 dBuV at
its output (prefer 0 to 6 dBuV). Connect the CMAP's Connector B to the tap's output
using an RG6 quad shield cable.
NOTE: You may use the CMAP's loop-through function on Connector A to measure the
downstream signal level at the internal cable modem. Connector A's signal level is
approximately 9 dB lower than the signal at the input to the modem.
You have completed mounting the CMAP on the cable strand.
You may now install the three external antennas. See
for more information.
