I’m almost done with building an RV7A as well. It has G3X and GTN750. I’m now looking for a traffic system for Europe without spending a fortune (new or refurbished, 8130 not necessary if from trusted source). I guess the only options with a decent utility in Europe are the TAS600/605 or GTS800. Anybody selling any or recommending a good source to buy one? Any other model I should look at?
I’m currently considering a Pilotaware install.

Until ADS-B is more wide spread the best useable systems are these systems. They don’t come cheap, and it will be hard finding a used one. There are good when properly installed and tend to stay in aircraft. You might also take a look at the L3 skywatch systems, which are similair, or to the L3 Lynx NGT-9000+ which combines a mode S transponder with ADS-B IN and OUT with an active traffic device, to detect non ADS-B mode A / C / S targets.
How long has the NGT-9000 been out?
When I was researching active TAS options, everybody I could find, including everybody who has installed one, involved the Avidyne (formerly Ryan) boxes, and Garmin in a few cases.
My TAS605 works OK but the 12 o’clock range is only about 2nm. This is probably the antenna position and I wonder if another system might be more sensitive?
There is also display device compatibility to consider. The Avidyne boxes drive most stuff, via ARINC429. When the RAF had the famous 2xGrob mid-air some years ago, Lees Avionics in the UK got the contract to fit the TAS6xx into every one and they installed a Sandel SN3500 EHSI as the display device. That is what I have too (2x) plus an old KMD550. Actually it was hilarious that the RAF went this way instead of promoting the “Mk 1 eyeball” more heavily (it’s like god asking the devil for advice) but that is another debate

Just over a year. Do note there are some diffent versions. The NGT-9000 (without plus sign) doesn’t have active traffic, so for requested solution only the NGT-9000+ would do the job. An online simulator is available here and available as app for IOS and Android.

While it can drive quote a lot displays over ARINC 429, it also can do this for most boxes over RS-232. the preferd methode would be to use RS-232. The ARINC labels limit the amount of data which can be displayed over ARINC 429, while it also lacks control from display to TAS box. The non A models can have upto four RS-232 displays, and the dash A models can have upto six displays. On TAS installations I usually wire to all possible displays, enabling traffic to all displays. The customer can then try and see which display he likes best. Traffic on the other displays is either left on or disabled in configuration depending on which display the customer likes best.
