What brand/model 12v GPS antenna is being used, reasons?
R
Linx Antenna Factor
ANT-GPS-SH-SMA (with SMA connector)
ANT-GPS-SH-MCX (with MCX connector)
ANT-GPS-SH-MMX (with MMCX connector)
Each GPS engine provides phantom power, and the voltage from each is added. If you use a standard puck the voltage from 2 or 3 engines will be too high.
The Linx has higher gain with higher phantom voltage (up to 12v).
System Gain: 28dB (typ. includes 4dB
cable & filter loss)
Noise Figu 1.8dB @ fo, 2dB max.
Input Voltage: +2.5VDC to +12VDC
