I am trying to receive one station- WYOU DT, Real 13, (22.1)
71 miles, 2 edge. I have a 7777 amp, Need to choose an antenna. Cannot find a Funke 1922, or the VIP-306 and VIP-307- all which seem to be the best of the bunch for this station. I still don't understand why these antennas are gone when they are in demand. Here is the info from TV fool, please let me know if you guys have an alternate recommendation.

Even without WNET in the picture, I doubt WYOU-13 would be reliable enough for regular viewing.

The difference in signal levels between WNET and WYOU is 27.5 db. You need 16 db more for WYOU to capture over WNET. Therefore, you would need a front to back ratio of 43.5 db for reception of WYOU.

There's one hope, a group of 4 of stagger stacked and horizontally stacked Antennacraft Y10-7-13 antennas. The F/B ratio of the antennas might be 15 db. The stagger stacking can gain another 15-20 db. The trick is to get the horizontal stacking distance far enough apart to null WNET at 187 degrees. That should net another 10-15 db of rejection.

These numbers are theoretical and any object that could reflect WNET into the antenna would ruin the calculations.

I have actually built such an antenna for analog channel 13, but it is no longer in service. It served to receive Albany's WNYT in Utica, NY when both WNYT and WHAM in Rochester, NY shared channel 13.

Thanks alot for your help. It is amazing how smart some of you are on here. Thank you all for taking the time saving me from trying the (almost) impossible. This is a great forum.

I don't think you need the same ratio as you need for S/N. I've been told that the "capture ratio" for FM radio signals is much lower than the minimum S/N ratio. FWIW, when I am developing filtered headends, if my desired signal is half a dozen dB above the same, but out-of-phase, undesired signal coming off another antenna, that is more than enough differential for a reliable lock.

Tonight or tomorrow, I will be pulling a couple of agile, heterodyne converters out of a headend, so if time permits, I'll try setting them on different input channels but the same output channels and mixing them, to see how much differential is needed.

The works has been done already. The desired to undesired ratio is 15.5 db.
