I have a GDL39-3D for ADS B in to a Garmin 660 GPS. For ADS B out, I have a Garmin GTX 335 with built in Waas GPS and altitude encoder. If I were doing it today, I would lean to micro Avionics. Things are changing quickly.

You guys all have some great "words of wisdom." Phil, I think you're absolutely right, wait until I'm ready to install, then decide what exactly I want.

I now have a Trig tt31 transponder. When I bought the plane, it had a kt76a. The trig is a direct-slide in transponder to the kt76a tray. I think all I need now is a trig tn72 receiver and ta70 antenna (about $700 for both) and should be ads-b compliant. Still looking into that.

I have the Dynon Skyview system and bought their mode S remote transponder (made by Trig I believe). When I was ready to add ads-b out the transponder was already compliant and all I had to do was buy a new WAAS GPS antenna puck.

If you have an EFIS (and in particular MGL) then the Trig transponders tie in very well. You can buy just the TT21/TT22 box (remote transponder) and control it through the EFIS, so have no panel-mounted heads.
For me this is great, as it means the EFIS provides the extended squitter of the Mode S transponder with the GPS position and, thereby, provides ADSB Out. This is permitted under the 'experimental' rules of the UK and is a simple and cheap way of ensuring more people have ADSB Out (it is not mandated there). I do, however, appreciate the rules are different in the US but it might be an option to use for those aircraft that won't have ADSB mandated but think it's a good idea to have it.....just in a cheaper form.
