You can use antenna extensions to mount the antenna remotely in an area with better cellular 
signal and greater mounting space. For antenna extensions, use the same internal cables as 
when you mount antennae directly on the FACU. Rules for mounting antenna extensions are less 
restrictive than for mounting on the FACU. 

Antennae are pre-installed with the extension and wall brackets in antenna extension kits. Consult 
the following guidelines before installing the antenna extension:

•

You can place holes to mount antenna extension cables anywhere on the box. Ensure that
the 36 inch cable can reach the mounting hole from the cellular module location, which is
usually in the top bay.

•

You must leave a minimum of 3/4 inches (19 mm) around the center of the antenna cable
connector for ease of installation.

•

Always mount remote antennae vertically.

•

Antenna extension cables are power-limited.

•

If you mount more than one antenna, mount the extended antennae at least two inches apart.
Further than two inches (5 cm) apart is better.

•

You cannot link antenna extensions together. Use only one extension for each antenna.

•

Use the full length of the antenna extension cable. Do not cut or splice the cable.

•

Coil excess cable near the FACU. Do not coil the 15 foot extension cable tighter than a six
inch (15.3 cm) diameter loop. Do not coil the 15 foot and 25 foot cables tighter than a 12 inch
(30.5 cm) diameter loop.

Consult the following guidelines before mounting the antenna on the CSGM External Box:

•

Antenna holes are pre-located with knockouts in the CSGM External Box. Choose any two of
these holes to mount the antennae.

•

Mount the primary antenna vertically aligned.

•

The cellular module kit for the external box comes with a shorter antenna cable that reaches
all of the knockouts in the external box.
