In almost all markets the ATSC 3.0 transmitter is a
single lighthouse source which is used by all the
local stations.  The location and power of the
the transmitter, and what antenna radiation
pattern is chosen for coverage, may have
differences from other transmitters in the market.
If you really want to know, the FCC database
has all the details, although I think some web
sites try to distill the information into something
more accessible to the average tv owner/viewer.
In addition, some markets will transmit different
PLPs with different tradeoffs (robustness vs
resolution) at the same time, to deal with
challenged reception cases or to choose to
test the highest quality at the expense of
coverage.  ATSC 3.0 gives broadcasters a
lot of options, and it is not unusual that over
time a number of those options get tested to
see what works best in that market (I have not
heard of anyone doing SFN yet, but that too,
will likely be tested as time goes on. especially
in markets with classic translators).
