Since the info you provided shows you are at the far fringe and most possible channels are UHF, I would suggest trying a DB8e and a juice preamp as a minimum

The db8e is slightly better but twice the size and half the beamwidth

A 2 bay bowtie will likely be your best option since all your line of sight stations are UHF.

There are many 2bay bowtie antennas on the market starting as low as $19.99

You may be going under an obstruction like a tree canopy for example

Yep, sometimes you can move 1/4 wavelength up or down the mast and go from nothing to great.

Also 100 ft of coax has considerable loss at UHF frequencies so if you can shorten it up it would help
