Troubleshooting - Antenna

This troubleshooting guide addresses potential failures that will affect the antenna per-

formance of the phone, and discusses methods for correction of these failures.

For additional information, refer to the Eagle Antenna Electromechanical Specifications

(DMS03311-EN-2.0) and the Eagle Antenna Module VQD (DMS00188-EN-1.2).

A properly installed and plated Eagle antenna module is shown in Figure 1.

The Eagle antenna module consists of the internal antenna and whip antenna as one

module.

If the Eagle antenna module is missing, install one. If an unplated internal antenna is

installed, replace it with a properly plated internal antenna module.

If no internal antenna is installed, the antenna gain will be degraded by more than

25 dB.

Figure 2 shows the RF feed and ground stamped contact spring clips properly installed.

Figure 3 shows both stamped contacts spring clips missing. If the either contact is miss-

ing or bent, replace antenna module with new antenna.
