NPD-1
Troubleshooting — Antenna

Bottom antenna clip bent or missing

The bottom antenna clip is located near the bottom of the phone in the D-cover. A prop-
erly installed bottom antenna clip is shown in Figure 4.
If the bottom antenna clip is bent or missing, then it should be carefully replaced with a
new one.
The degradation in antenna performance is only about 2 to 4 dB in the receive portion of
the CELL band when the whip is retracted. PCS band, retracted whip, degradation will be
10 to 15 db.

Missing whip

If the whip is missing, then the Eagle antenna module should be replaced. Figure 5
shows a properly installed whip antenna.
