Detuning Circuit for Bottom Antenna Clip

Figure 9 on page 10 shows the bottom antenna clip. The detuning circuit is right next to
the bottom antenna clip. If the detuning circuit is not installed properly, then the
internal antenna gain will degrade by about 4-5dB at Cell band and 3-10dB at PCS band.
The GPS antenna gain will be degraded by more than 2 dB with the whip in the retracted
position. The detuning circuit consists of a 1.2nH coil inductor and an 8.2 pF capacitor.
• If either the inductor or capacitor is missing, install one.
