How cheap can I get ADSB for if...
 

I have a Garmin 430W and an encoded GT327 in my -10.

Adsb out is all I want. I'll use my eyes for the "in" part.

Best,

Eyes
 

My eyes are not getting better as I age. Are yours?

The ADSB planes I fly show me traffic I can't see all the time. It's scary sometimes!

TIS-A
 

I have had TIS_A from about 2008 and of the traffic displayed on my screen I've only "seen" about half of them, no matter how close. Sometimes my 430 alarms with a traffic alert, less than a mile away, still can't see some of them. Yes, I know, if you make a turn the traffic just might be me. A failure of the system.
Anyway, I agree, it's scary.

The cheapest and best way to go would be a Trig TT22 transponder. Super easy to install and use. You can get a GDL 39 later for ADSB in.

Pierre,
I thought I replied before but I guess it did not take.
Agree with above, least expensive is to sell your 327, put in a TT22. You may also need a $100 software upgrade to your 430W so that it puts out data in Garmins ADSB+ format. The EXP UAT is close in price (you need antennas) if you want to go the UAT route. ADSBin (if you go the TT22 route) only adds $500 or so, depending on what you already have in the panel.

Same here
 

Ive got a similar setup. 327 and certified garmin gps. Since its only a transponder swapout, I'm thinking I'll hold off a couple more years.

Why Trig TT22 the cheapest?
 

NavWorx ADS600-EXP is $1,149 plus antennas, harness, TRANSMONSPE and hardware kit. The total is still less than $2,000 ($1,914 in my case).

FreeFlight RANGR 978 Lite is only $1,995 including antennas and installation kit.

I believe both above units include built-in WAAS GPS meeting ADS-B out requirement, although the OP stated he has a 430W which may need software update to talk to Trig TT22.

Unless flights outside of the U.S. are required (which require S mode), otherwise, NavWorx and FreeFlight seem to be less expensive than Trig TT22.

Garmin and Trig
 

Sometimes I'm not a favorite of Garmin but in this case with a Garmin 430W
a better choice would be a Garmin 330ES transponder. It's about $1000 more
than a Trig but the software communication is the same meaning when you have problems, it's a single phone call to Garmin to sort out.

I have a Garmin 430 (not W) and a Garmin 330(not ES). My choice will be to convert them both. $5000, yep... Both have served me well, why change.

Trig manual:
Note: The TIS output and GPS input speeds are not separately
controlled on the TT21/TT22. Not all combinations of GPS input and
TIS output will be usable if the external devices operate on fixed bit
rates and are different to each other.

While this is probably not a problem, the Trig is a Scotland product and they have different rules regarding ADS-B..... I think.

Well I would assume that since the Trig TT22 is STC'd for installation using the 430W as a position source I would assume there would be no problems. The Trig unit has proven to be very reliable, just ask any Dynon or AFS user.

It's because of what he already has. No need for a gps if he already has one.
TT22 from GRT (no control head, GRT Hx will control): $2200
Garmin 430W software upgrade: $100 or less
Buy ADSB-in box compatible with HX: $500 (optional)
SELL existing Garmin 327: -$900 to -$1000
Re-use antennas, coax, breakers, Net cost: $1800-$1900
EXP is not all that different but you do have to install two antennas, breakers, etc. And mode SES solution works if you ever travel somewhere (Bahamas?) where it's needed.
re Trig: the TT22 and 31 now have US STCs available when used with Garmin navigators, so yes they work.
