4.1.6 Human Exposure To Radio Frequency Electromagnetic Fields

For fixed applications, antenna gains and mounting techniques can vary

depending on the application. Antennas suitable for use with the MCC-

545C are listed in the MCC-545C RF Energy Exposure Guide. It includes

details on the human to antenna separation requirements for specific

fixed and mobile antennas with various gains.

Always disable the transmitter when working on the antenna and/or co-

ax cable.

4.2 Equipment Installation

The MCC-545C operates over a temperature range from -30°C to +60°C

and is housed in a stainless steel enclosure that can be used in a wide

range of applications.

4.2.1 Mobile Applications

Mobile applications can include vehicles, aircraft, vessels, and

locomotives. Each application may require a different type of antenna.

For example, a 3' base-loaded ¼-wave whip is generally a good solution

for vehicles. Low profile antennas, vertically polarized, are required for

locomotives. 10' ¼-wave whips are generally used for vessels; these

antennas should be designed for operation in maritime environments.

Refer to the MCC-545C RF Energy Exposure Guide for more antenna

information and means to limit RF exposure. MCC’s engineering services

department can be contacted for specific recommendations.

For vehicle installations, the MCC-545C may be mounted in any

convenient location (e.g., in the trunk, under the seat, or in the engine

compartment).

Refer to Appendix E for a list of example equipment components

required for an MCC-545C used in a typical mobile application.
