He might be equipped, but I wouldn't see him unless I'm getting the TIS-B re-broadcast of ATC radar data. He would be transmitting on 1070, mode S and I'm listening on 978 UAT. I only have single frequency ADS-B in.With no reception, I only see those with UAT 978 ADS-B out. The dual band receiver might be a good idea.
A friend of mine who works at a major jet avionics retrofitting outfit in Van Nuys tells me that a whole lot of jets are not fitting ADS-B because they don't want the downtime and lost revenue. When they wait til the end, they'll probably find out that the downtime will be a lot longer while everybody tries to get legal all at once and they are grounded until they can comply.
Yes, I commonly see traffic of all types, including jets on the ILS, when I have TIS-B coverage, which has been pretty much all the time. I've gotten used to it. That's why I was a bit surprised to physically see the aircraft, but not see him on my EFIS. It is easy to become dependent on this technology and complacent. My scan will now include frequent checks to see if I have contact with ADS-B ground stations and will still take what I see with a grain of salt. Just because it isn't displayed, doesn't mean it isn't there.

A Gulfstream will need to have a mode S-ES transponder, so maybe they?re waiting for a scheduled transponder check before upgrading?
Have you seen other ADSB traffic on 1090 MHz (e.g., any jets)?
