The issue will always be KCPQ-the FOX station, whose tower is about 25 miles west of the other Sea-Tac stations. a single antenna, no matter how powerful, won't see KCPQ adequately without a rotator OR a separate antenna aimed at the KCPQ transmitter. In your situation, I would use a 2-antenna system consisting of a Winegard HD-7696P aimed at 320 degrees AND a Winegard YA-1713, a high-band VHF yagi, aimed at 275 degrees. Separate the two antennas n the same mast by 4', and mount the lighter YA-1713 at the top of the mast. Combine the signal from the two antennas using a Channel 13 Channel Master Join-tenna, which is available from Warren Electronics. Then run the
output of the Join-tenna into a Winegarrd HDP-269 high-input preamplifier, and mount a 3-4 way high-quality splitter in the line AFTER the power injector for the preamp. Once the signal is at the splitter, make your cable runs to various TV sets throughout your house. This combination will allow you to see ALL the major Sea-tac stations, and will insure enough signal that each TV set will function properly on all the channels. Good Luck
