"szilagyic" wrote in message oups.com... Hello, I have two antennas that I am trying to combine, and have a question in regards to the best way to do this. The first antenna is a Winegard HD7084P (FM/VHF/UHF lpda) that is hooked to a preamp and tuned in perfectly. I want to add my other antenna (Winegard PR-8800 UHF bowtie) that is also tuned in and points in the opposite direction (almost 180 degrees) to pick up some UHF stations. .......................................... Over the past 50 years several antenna manufacturers have come up with kluged arrangements to do what you propose. None worked, except in a few special cases where the signals were very strong. What you need is an antenna rotator, or a second antenna with its own feedline. When you combine the outputs of two antennas without appropriate filters, not only is there a chance of signal cancellation, but you will also quite likely have a severe echo problem. Tam I wanted the same set up as you did using a Winegard HD8200P (combo) & HD9095P (UHF). In the end I unhooked the UHF in the HD8200 and get VHF (from the 8200) from one direction and UHF from another direction. I could not combine the two and receive a good UHF signal. I will say that my HD9095P does recieve one channel 180 deg from where it is pointed. You might want to play with the UHF reflectors (try folding them down some maybe) to get more 180 deg. signal. |
