Operating Manual

PRELIMINARY FCC ID: BIB61201001 INTALLATION 3-5
PRELIMINARY MCC-6120 SDR Packet Data Radio Network
3.2 Equipment Installation
The MCC-6120 SDR operates over a temperature range from -30°C to +60°C and is normally
housed in a stainless steel enclosure; however, it is not waterproof.
A NEMA waterproof enclosure is recommended for outdoor installations. To ensure proper
operation, shielded cable is recommended for all connectors. Always use adequate strain relief
on all cables and a weatherproof seal at the entry point of the enclosure.
If the unit is housed inside a restricted enclosure care must be taken to remove excess heat from
inside the enclosure. The MCC-6120 SDR will consume 12-15 watts in a receive-only mode.
While transmitting, the unit can consume up to 150 watts. Operating at a 10% duty cycle will,
therefore, result in a power dissipation of about 30 watts.
3.2.1 Mobile Installations
Mobile applications can include vehicles, aircraft, vessels, and locomotives. A different type of
antenna may be required for each application. For example, a 3’ whip (at low band or high band
VHF) is generally a good solution for vehicles. Low profile antennas, vertically polarized, are
required for locomotives. 10’ whips are generally used for vessels; these antennas should be
designed for operation in maritime environments. Consult with the MCC sales department for
specific antennas recommended.
For vehicle installations the MCC-6120 SDR may be mounted in any convenient location, e.g.,
in the trunk, under the seat, or in the engine compartment.
3.2.2 Cable Connections
There are a maximum of eight (8) cable connections to be made to the MCC-6120 SDR as
shown below. These connections are used for both mobile and fixed site applications.
IMPORTANT
Before installation and use of your mobile 2-way radio, read the MeteorComm RF Energy
Exposure Guide which contains important RF energy awareness and control information and
operational instructions to ensure compliance with the FCC’s RF exposure guidelines.
