3.2 Antenna interface details to iWave GPS module
Only Active Antenna support is provided, 2.85V is provided to external connector.
Gain of the Antenna tested is approximately 28 +/- 2 dB.
Recommended LNA gain of the active antenna is 16dB < 28dB
Better to have noise figure < 2dB.
External antenna should work with 2.85V.
SMA connector is used to interface external Active antenna to iWave GPS Module.
