2.8 Antenna Interface
The antenna interface of the CM52 consists of a single or dual RF connector for the
radio with optional antenna diagnostics, and a single RF connector for the optional GPS
function.
2.8.1 Antenna Connector
A variety of antenna connectors are available for the CM-52 module including SMA,
SMB, MCX, and BNC. A standard 5-pin, thru-hole pattern has been selected because
of the wide variety of compatible connectors available and also for the maximum
mechanical strength.
For automotive applications, a FAKRA-type connector is available which provides a
double locking mechanism as well as a keyed, color-coded interface as shown below:
