Was the antenna aimed at WLIW?
How dense are the trees? Can you post a photo?
I would point long-boom Yagi at WLIW.
Options in order of preference:
Antennas Direct 91XG
Winegard HD9095P
Antennacraft MXU59
Channel Master CM-3023
Antennas Direct 42XG
Winegard HD9075P
Antennacraft MXU47
Channel Master CM-3022
The longer versions are preferred for their ability to reject multipath and reduce or eliminate the need for a preamplifier.
