Your report shows that the available broadcasts are from the same general direction. That's very helpful because you can expect to find a single antenna that will receive all available signals without the need to rotate when changing channels. Also shown on your report are the real channels used by each station, this helps determine the type of antenna.
In this case, you have signals in the UHF band (real CH-14 and higher) as well as a few signals broadcast on High-VHF channels (real CH-7 through CH-13). You'll want to use an antenna that is designed to receive both bands (UHF and H-VHF).
Next, the report lists the predicted signal strength of each signal. The NM value is easiest to use IMO. Up to a point, the higher the number the better... almost all are double digit positive values, which means you should not need to use a extremely large antenna to get enough signal.
If I was in your situation, I'd opt for an antenna such as the Winegard HD7694P or Antennacraft HBU-33. I'd start with the antenna pointed at about 315° per a compass.
Mounting outdoors, clear of obstructions such as buildings (including your house) trees or other vegetation will give you a far better opportunity for reliable reception.
After looking at the list of stations in the Hilo area (as shown at

Are you planning to connect more than one TV? if so, how many?
How long a cable will be needed to get from the antenna to the farthest TV?
