Also far removed from amplifiers and their operation - more appropriate
for a DTV antennas list.

A twinlead folded dipole "FM Antenna" (88-108 MHz) is not very good
on UHF TV (450-900 MHz). It has a widely varying pattern and on some
channels appears as a resistive short across the receiver input.
If you get any where near acceptable signals with the FM dipole, all
stations are in a single direction (+/- 45 degrees or so), and all
stations are UHF (actual channel - not the virtual channel they ID),
then a two or four bay bow-tie antenna will be more than enough and
probably far more reliable than the amplified omni. On the other
hand if you are in one of those places "between" transmitter sites
(with clusters in opposite directions) you're likely stuck with an
omni (or multiple directional) antennas.

Your area has two high VHF channels and many UHF channels (19-47).
Fortunately, other than one distant independent, they seem to be
clustered in two directions with less than a 30 degree spread.
You would probably be best served by a small VHF/UHF dualband
log-periodic - a UHF "bow tie" antenna would be questionable for
the two VHF stations.
