Too many GPS puck antennas
I just started pimping out my ASW20. I am putting in a LXNAV S100, FLARM and an ADS-B Trig transponder. Thant’s three puck antennas and I haven’t even figured out where to put the FLARM antennas yet! Does anyone have a good solution?

Does anyone have a good solution? I've been using a MECA divider for several years now. Besides the panel being less crowded, GPS satellites aquire much faster. Don't use DC blockers. Use a 12v GPS antenna to feed the divider. This way if your primary device fails, you don't lose all of them. Search for GPS divider in the subject, links were posted on a previous thread. Jim |

Does anyone have a good solution? Too many puck GPS antennas too close together will lead to interference and poor function. I remember reading somewhere that these puck antennas must be 30 inches apart to help reduce the possibility of such interference. |

Too many GPS puck antennas
I put a couple on my canopy rails.Â* Most (mine, at least) GPS pucks have
a magnetic base so I glued small steel washers to the glare shield and slapped the pucks in place.Â* No worries when jettisoning the canopy.

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 Jim |

Later, I removed the 302 and put in a Butterfly vario, using it's supplied GPS antenna.
