Skybeacon only provides ADSB out. Simple install. Dependent on how decent your existing transponder is so make sure it is working correctly. Will need to tweak the threshold value (lots of threads on here about that). Can be installed in the wingtip if that is a configuration that might make sense for your specifics.
