teleview

Yes the DB4e is the antenna to use , I had confused you with another question asker , (a very rare event).
It is the talk of the Pine trees that through me off , got me to thinking about Oregon.
I reread my posts so I can clarify the information. I removed that bit information that does not apply to your reception situation.

The reception will be Ok.

From what you describe the trees are not that dense to the west north and become less trees to the north west.

And that direction is where the group of Tv transmitters is at.

Go to the tvfool radar plot report and click on the , Pending Applications Included , Only Digital.

You will see that the main group of receivable Tv transmitters is to the north/west.

And there is one Tv transmitter off to the west , WYDT-CA channel 26.

The programing is , Tach Tv a hot rod car channel and Weather Nation a weather channel.

The 310 degree aim direction is a in between aim direction between the main group of Tv transmitters to the north west and WYDT to the west.
