I have been experiencing multipathing problems with only channel 13.1 in the Hampton Roads area of Va. I did replace the channel master stealth with the radio shack 2016 yagi style directional antenna. It solve most of my problems except for channel 13.1 (ABC). So I called Voom yesterday and they are going to be coming out and installing a Wine Guard PR-8800 (8-bay antenna). Is anyone on the board using this type of antenna? How is it working?
