Step 2:
Measure the cable distance between the Dipole Antenna
and the ATU. It should not exceed 20 feet.
Step 3:
Cut a length of cable that equals the cable length
measured and attach the BNC connectors to both ends of
the RG-58/U coaxial cable (See
Appendix A: Coaxial
Cable
, page 101).
Step 4:
Connect one end of the cable to the Dipole Antenna.
If the Dipole Antenna will be exposed to the weather, treat
the connection with RTV rubber silicone sealant after
everything is installed.
Step 5:
Connect the other end of the coaxial cable to the
Antenna
RX
connector on the ATU.
Note: Do not dress-wrap or tie-down the cables until the
system has been tested.
Step 6:
Turn on the system and adjust the ATU in accordance with
the instructions in the
Maximizing Antenna Performance
with the ATU
section, page
