Trig TT22

[Browncbr1]

My plane is about to go in for a gtn650 and dual G5 install.  I decided to hold off another year or two on adsb out, but I had been thinking about the Trig TT22 as the upgrade path   

I like how it is so small and light and has an integrated altitude encoder.  I understand I'll be able to use the gtn's waas source for the adsb and the I THINK the gtn will be able to control it remotely as well.   At $2k, this seems like the best path for me as it is today.  

Does anyone have any other suggestions of other value transponders I should look at? Pitfalls with this unit?   I prefer to do a transponder unit in order to pull out the old narco.    

Thanks for any input guys!

The only thing small about the TT22 is the control head that install in the panel. The remote unit is the actual transponder that need to be connected to the control head. You need to find accessible space where to locate the remote unit. I myself prefer the standard one piece transponder. Easier to install and bench check.

Hi Jose,

thanks for your input.  I had consider this and it seems there will be ample space where the current encoder box is located.   Access is pretty simple.    I know the GTn can provide position source, but I'm just unclear if the GTN650 can actually control the TT22.    For $2k, I don't know of a better option to become adsb compliant, while getting a new transponder and freeing up enough panel space to fit an iPad mini on the right side.

I found a 330es that will work out to be about 1.3 AMU (self installing)... but that’s about as CB as I think  you can get for ads-b

The TT22 Installation Manual does not mention remote control other than with the Trig TC20 control head.

It can't control a Trig. The GTN650 can control a Garmin GTX345R, 335R, 33ES, all of which are ADSB-out

Thanks for confirming that.  Perhaps I'll go the Bradp route and find a used 330ES,,, but I'll have to decide if fitting my iPad mini on the right side is more important than controlling the transponder with the gtn or not.   I doubt both would fit.

Sounds like a great CB option!  Thanks!

If you are tight for space, you might want to save up and get a remote version transponder. Just a point of reference, I had a GTX-327 connected to my GTN 650 and found that 99% of the time,  even though I could control the 327 from the GTN, I ended up using the 327’s buttons. So, even if you have a button version that is compatible with the GTN, you can use either.

As someone who has learned a lot about avionics upgrades, to save money, try to get as much done at the same time as you can. My plane went through significant upgrades in 2012, 2013, 2015 and 2017 (and probably some minor ones along the way). If I were to do it again, I would have held off until I could group more of them together.

thanks for the advice Marauder,... I had looked at the remote transponder boxes, but they seemed more expensive, not less expensive for some reason, plus they all need an additional encoder box.. I know they are just around $300 and could probably use my existing one though...    I'm not sure if behind panel space would become an issue, so would need to check..     Comparatively, the trig remote box is much smaller and doesn't need the additional encoder box.  I also like the idea of having the option of independent operation from the GTN, as you pointed out.

Great minds think alike!!! This is exactly the upgrade I am planning until my wife changes my mind. My XPNDR solution at this point is the Stratus ESGi. I like the ForeFlight interface and it would give me 'dire emergency' AHRS if needed. I also have the Narco and with the ESGi it all goes in and behind the panel.

The ESGi is exactly what I has planning before I started looking at the TT22 due to the integrated encoder and my desire to put an ipad mini on the panel.

The thing I don't like about the ESG is that I understand it only integrates with a stratus, hence foreflight.    I have a stratux and am happy with subscription free fltplanGo.. 

If I wasn't getting a GTN, then the ESG would be the way to go..   I like that they started making the ESG without WAAS source at a lower price though..   

 

With redundant G5s with independent batteries, I feel ok about not having another ahars.   I also already have a dynon D2, which I'm vacillating on selling after the 2x G5 upgrade.  Selling the D2 would go a long way to pay for an adsb transponder!
