Greetings,
The issue you have is that your Portland Stations come
from several different directions to your home. Another
consideration is that you need both VHF and UHF capability.
It would be challenging for any one antenna to capture
all your signals without a rotor. The other option would
be two antennas, one pointed Northeast and the other,
Northwest. What is the proximity of any trees and their
height to your home? What are you willing to spend for
good, consistent reception? Cannot really make any
recommendations without more information from you.
