Looking at the Radar Map shows Tv stations to the , South East and to the South , the Tv stations are spread over a wide angle.
So the HBU44 antenna is selected because the HBU44 has a Wider Forward Angle of Reception.
The forward angle of reception is also known as Beamwidth.
The HBU55 and HD6798P antennas have narrower beamwidths , a narrower beamwidth is not good for your reception situation.
------------
Maximum antenna gain is not the , be all and end all , when the signal reception is reduced at forward angles to the antenna because a narrow forward beamwidth.
------------------------
An alternate setup I can recommend is a 2 antenna setup to cover the wide angle of reception.
Install a ,

Y10-7-13 VHF high band channels 7 thru 13 antenna aimed at about 154 degree magnetic compass direction for reception of , WVNY-DT , ABC , Real VHF high band channel 13.
And install a , Antennas Direct , DB8e , current UHF channels 14 thru 51 antenna.
Aim 1 panel at about 160 degree magnetic compass direction.
Aim the other panel at about 140 degree magnetic compass direction.
-----
Install the Y10-7-13 antenna about 3 feet below the DB8e antenna on the same antenna mast/pipe.
----
Install a ,

10G221 preamplifier.
-----
Connect the Y10-7-13 antenna to the VHF connection of the 10G221 preamp.
Connect the DB8e antenna to the UHF connection of the 10G221 preamp.
------
Home Depot has , TOP RAIL , chain link fence , PIPE , that makes good antenna mast/pipe.
The sizes are ,
10 feet - 4 inch long , 1 and 3/8 inch diameter.
and
10 feet - 6 inch long , 1 and 3/8 inch diameter.

Here is important information.
Some of the signal strengths of the Tv stations you will like to receive are Weak Signal Strengths.
Avoiding obstructions to reception in the directions of reception is Important.
