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 MCC’s 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.
