5. Verify that the O-ring for the surge arrestor is in place and is
located on the inside of the Gateway enclosure.
6. Attach the internal coax cable to the surge arrestor.
7. Install the external cellular antenna, mounting the antenna
higher than the Gateway to obtain better service reception.
An optional wall mounting kit (Neptune Part No. 13145-000) is
available for the external cellular antenna. The kit includes a
5-foot mast and wall mount brackets.
8. Connect the 6-foot coax cable (included) from the Gateway to
the external cellular antenna.
Longer coax cable assemblies (terminated) can be ordered, if
needed, or refer to the coax cable matrix (Table 32 on
page 104). The coax cables are available in lengths from 10
feet to 40 feet. The LMR-400-UF and LMR-400 by Times
Microwave are acceptable coax cable types for use up to 40
feet. Use Andrew Part No LDF4-50A for coax cable lengths
greater than 40 feet.
9. Weatherize the coax connections using the weatherization kit.
