Transponder installation article- Soaring Magazine
Within the past 2-3 years, someone did a very nice article on installing a transponder, I believe it was a Trig21 or 22, in their DG303. I've searched but can't find the article/issue. Does anyone recall this or happen to know the issue?
Thanks |

Does anyone recall this or happen to know the issue? Thanks I installed a Trig 22 in my Stemme and one in my gyroplane. It's straight forward especially if you also buy a pre made harness. Simply: 1. Find a place and install the remote box. 2 Install the control head in the panel. 3 Connect the control head with the remote box using the purchased cable. (You can make your own cable if you're handy with that, the connectors and pins are included with the transponder. 4. Connect 12v and ground to the red and black (respectively) wires. 5. Connect the static line to the static ports using the supplied T-fitting. 6. Install the antenna and connect the coax to the transponder 7. Power on and configure per the instructions. If you're also installing ADS-B, it's even easier than the steps above: 1. Install the GPS, 2. Connect the GPS to the transponder. It's powered via the Y-cable (ordered separately) 3. Mount the GPS antenna and connect the coax cable. 4. Power on and configure per the instructions. Hope that takes the mystery out of it. -- Dan 5J |

This check must be repeated every 24 months. https://www.law.cornell.edu/cfr/text/14/91.413 Tom |

Transponder installation article- Soaring Magazine
A few random notes from my TT22 installation:
- From the Trig Installation Manual: "The transponder power input is not protected against reversed power connections. Reversing the power and ground inputs to the transponder will destroy it. Check wiring before applying power." -- A proven hazard demonstrated (luckily) by someone else - Common sense for all transmitters but not obvious on a transponder: Make sure the antenna is connected before any transmission takes place. When is that? Generally, anytime the transponder is on GND, ON, or ALT switch mode and it gets and replies to an interrogation. SBY mode use (e.g., for initial TT21/22 SETUP programming) should be OK without having the antenna connected. But it's easy to mistakenly turn past SBY onto one of the "transmit" positions. So it's best to have the antenna connected before powering on. - If you plan to have ADS-B Out by integrating a Trig TN70 or TN72, both the firmware on the TC20 control head AND the main transponder (TT21/22) must be of a certain version number or later (like v1.14 and v2.12, respectively). An authorized Trig dealer can confirm the current requirements and upgrade your firmware as needed. -- The firmware versions are displayed very briefly on the control head screen after powering on. I video'd the sequence and replayed it several times to catch the numbers. |

I am thinking of installing a TRIG xponder for next season, maybe with ADS-B, but this would mean installing multiple GPS antennas (FLARM, C302, Xponder) and I'm running out of room under the glareshield. Questions for the experts out the need there be a minimum spacing between GPS antennas (i.e. do they interact); and is there a way to connect one GPS antenna to feed one or more boxes? Thanks!
