This last weekend I installed two of Dynon's new SV-ADSB-472 in place of existing SV-ADSB-470s. A few observations; the new 472 is significantly smaller and much easier to mount in tight places compared to the 470. I didn't have any issues with the D9 and co-ax connections being on opposite ends on the 472, just had to re-route a few wires to accommodate re-routing the co-ax. Performance wise, the new 472 is a significant improvement in ADSB traffic awareness. During my operational checkout of it, I went to several areas were previously I had no ADSB traffic due to ground station signal blockage. With the 472, ADSB traffic awareness of other ADSB out acft is significantly improved even when on the ground. Overall, the new 472 is smaller, lighter and provides significantly better ADSB traffic awareness than the 470 in some circumstances. It is well worth the trade in cost and effort to swap it out.
