I'm not sure if I was meant to respond to this, but I'll note the following:
- Yes, one of the antennas we tried was a 14-foot long model that filled
the entire room.
- I get good reception of both the VHF and UHF NYC-based analog stations
with just rabbit ears on the TV. For a New Jersey station, I sometimes
use a UHF loop.
- For Bob's most-recent test, we used a UHF loop taped to the window.
If I recall correctly, one of the cards nevertheless picked up WPIX-DT,
which is on channel 12.
- Yes, all of the NYC low-VHF stations are in UHF for DTT. WPIX-DT had
a UHF channel, too, but, after the fall of the WTC, I think they wanted
an adjacent channel for simplified transmission.
TTFN,
Mark
