Yes it is the CM4228HD 8 bay UHF panel antenna.
The CM4228HD is fair to good at receiving the VHF high band channels of 7 thru 13.
Your location has WICU-TV channel 12 NBC.
_________________________________________
The DB8e is a New antenna and I do not know how well it does on the VHF high band channels.
However , Yes you can use the DB8e antenna.
You might need to add a VHF high band antenna such as a Winegard YA1713 antenna.
And a UVSJ to couple the 2 antenna , DB8e and YA1713 , together.

Your reception situation is -->Experimental.<--
Your reception situation Requires more then extra effort to get the reception.
A -->Tall<-->Tree , the type and kind of tree that has 1 straight trunk that goes straight Up work the best for a tower to mount a antenna on.
A thicker diameter trunk is better , so that the upper part of the trunk does not sway so much in the wind.

Signal Strength 'In The Air' is way more important then any amplifier.
Getting a starting signal strength of -10 NM(dB) or better arriving at the antenna is a good starting place.
Will a tvfool radar plot antenna height of 100 to 125 feet do that at your location??
Looks like 1 of the posted antenna heights of 100 feet has a signal strength of , -6.5 NM(dB) , -6.5 is better the -10 NM(dB).
Thinking in Experimental terms.
And flexibility of thinking.
A straight tree can be used as a Test tower or a Permanent antenna tower.
If you have such trees , then the dollar amount to test or permanent mount antenna/s up high is a low dollar amount.
Falling out of a tree is Real Close To Zero Fun , so do not fall out of a tree.
___________
Here are more options for a permanent tower , Aluminum , Light Weight , Free Standing , No Guy Wires , Lay Over , Towers.
Do all antenna installation and aiming standing on the ground.

Your reception situation is Experimental so all manner of antenna heights and antennas and a Ultra Low Noise Amplifier is your lot in life.
