It's not a matter of seeing the big guys vs the small guys. Most pilots needing a transponder upgrade are going to go with mode-S 1090es. That is what all the Dynon units in Experimentals use. It's more a matter of being able to get a more complete and quickly updated picture when you are out of range of an ADS-B tower, typically when at low altitude near smaller airports vs only less complete traffic picture if out of range of an ADS-B tower, or even if you are within range of an ADS-B tower, getting slower traffic updates as you will be waiting for the ADS-B tower to rebroadcast vs receiving the traffic updates directly plane to plane.
However, it will work either way. It's only a matter degree as to how well it works. -Jeff Scott -----------? My opinion on the ADSB ?is that having the duel band receiver is nice but not really necessary. ?It is ture, you will not see the bigger airplanes and they will not see you if you are NOT in range of a ground station. If you are receiving a ground ?station everyone will see everyone. ?The only time you will be interacting with the big airplanes will be by bigger airports and they will have coverage from ground base coverage.If you fly alot in remote areas then duel band would be handy.This is what I've learned. ?My opinion might change when I start flying my plane.
