Too many GPS puck antennas
This has all been discussed here before. It's a bunch of over-conservative silliness about puck spacing. I actually did testing with different pucks touching each other and they all worked fine. It's better to use the puck supplied with the individual instrument as that introduces less opportunity for something to go wrong. And, if something does go wrong, lesser permutations as to cause.

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).

SH2 Series are DC 5V Richard |

I was puzzled about the assumption they were 12 volt antennas; don't have a clue, either. -- Eric Greenwell - Washington State, USA (change ".netto" to ".us" to email me) - "A Guide to Self-Launching Sailplane Operation" https://sites.google.com/site/motorg...ad-the-guide-1 |

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?- 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. What about compass interference with all those magnets and metal ? I have one that I moved around the compass but seemed to not affect it -- Delta8 Compass? We don't need no stinkin compass. ;-) 7Q |

Eric, They are not 12V antennas. Most if not all state of the art flight computer GPSs feed the antennas with 3v to 5v. Richard |

In Kansas, look at the GPS track when you want to know direction. Or pull out your iPhone, and use the compass app. -- Eric Greenwell - Washington State, USA (change ".netto" to ".us" to email me) - "A Guide to Self-Launching Sailplane Operation" https://sites.google.com/site/motorg...ad-the-guide-1 |

You can feed the S100 with flarm data which has GPS data
