So, TIS-B is data from ground stations. If you aren’t in line of site of a ground station, you wouldn’t receive the rebroadcast. I don’t get any TIS-B traffic on either the 8080 or 8978 pages - at least right now. I do see 3 or 4 UAT targets flying around my house.
I might be incorrect, but that’s what I read in that thread.
