With an HD7698P I'd predict that you'd find many days where KQTV would still be wiped out by interference. |
I did some research on this antenna and noted the gain figure provided by Winegard is 10.4 db for Ch. 7. But the gain for Ch. 7 on the HD 1084p and 7697p is rated at 10.9.
I think I have a solution to this problem. I did some research on head to head comparisons between the YA 1713 and Y10-7-13. A couple of people have actually modeled these two antennas and others have done some other tests with different signal strength gauges. All of these studies, and they are independent of one another. found the Antennacraft antenna averages a good 2 db more gain on virtually every channel than the Winegard model. One guy using four of the Y10-7-13's in Canada raved about how good this antenna is at rejecting channels off the side and back. He also said the gain was excellent for this antenna.
Unless I hear back from Denny's with a recommendation for something better, I plan to use the Y10-7-13 at 20 feet and a 91XG below it into a Titan 7777. This combination along with less cables and no coupler should yield the desired result. If that does not work then a horizontal gang will be the next step.
