Grounding

Proper mounting of the radio includes consideration for grounding. Please note that if the radio is attached to a metal pole that

is earth-grounded, no other grounding is necessary. If the radio is not earth-grounded via the mounting bracket, you must

attach a grounding wire to the grounding stud on the radio as in the adjacent diagram.

Shielded twisted pair Cat-5 cable is recommended for all installations. The shield within the Cat-5 cable does not need to be

grounded if the radio itself is grounded. It is important to consider that most Cat-5 cable will deteriorate over time if exposed

to the weather (especially direct sunlight). It is recommended that installers place all Cat-5 cables inside conduit. Plastic

conduit is sufficient. If metal conduit is used, it is not necessary to use shielded Cat-5 cable.

The Atlas4900-EXT is equipped with two reverse-polarity SMA connectors on the top for attachment to an external

antenna. Each SMA connector is labeled with either "V" for Vertical or "H" for Horizontal polarization. Connect each

cable to the appropriate "H" and "V" ports on both the antenna and the radio.

It is important to properly seal each antenna connection to protect against moisture and corrosion. Each Atlas radio is shipped

with a packet of Coax-Seal connector sealant which should be applied over each of the SMA connectors. Coax-Seal is a

gum-like tape which is applied by wrapping around the connector and then compressed/molded to form a single cohesive

protective covering over the connector

To properly apply the Coax-Seal product first wrap the connector as shown:

Secondly, compress the Coax-Seal product to mold into a single protective covering:

Important! Please note that the silicon strain relief has a small gap when the cable is

installed. This is normal.

It is important to provide strain relief and drip loop for STP Cat-5 cables. Do not mount the

radio upside down as water will enter the bottom of the radio and cause permanent damage

Important! The Power-over-Ethernet injector is not a weatherized device and must be

located either indoors or in a weather-protected cabinet.
