[QUOTE="Rickideemus, post: 133843, member: 12677"]Af, you have what's known as "translator hell" -- all those stations with numbers in the call letters. It's worse in your case, because somebody forgot to tell them they should copy the real RF numbers onto the virtual numbers with that type of call letter! So it's a real mess. You're giving all the virtual numbers -- the [U]FAKE[/U] numbers on your TV screen -- which tell us practically nothing. Especially since TV Fool reports cochannel interference problems on literally half the channels you might be seeing. So I plowed through [I][COLOR="#FF0000"]hell[/COLOR][/I] for you to come up with the following chart: [CODE]K30FN 5.1 ABC, 5.7 K21DG 11.4 NBC, 11,5 weather K26CS 2.1 PBS 2.2 MN, 2.4 weather K43JE 43.x latino K34JX 9.1 Fox, 9.2 MyN, 9.3 Movies! K41IZ 4.1 CBS K14KE 9.4 Bounce, 9.9 Fox K38MY 12.4 CBS, 12.5 Fox K44AD 5.2 Ind, 5.3 ME, 5.4 ANT, 5.6 ThisTV K32GX 23.1 CW, 23.2 Get, 23.3 Country[/CODE] These are all the "yellow" stations to your west at 266° magnetic. The real RF numbers are of course the numbers in the call letters -- all UHF. It looks like a very full lineup with all the most popular affiliates. I looked at the three charted stations where cochannel interference is flagged, and it doesn't look like that's any cause for concern. No way to tell, at this point, whether the cell/water tower is causing a problem. Certainly if you can get everything on the chart, you should be very happy! Since all these great stations are in the same direction, and you have interference to worry about, conventional wisdom would point to a large UHF Yagi antenna like the Winegard HD-9032 or HD-9095P. No idea why you would want to point it that way. Anything NNE is waaaaaaaay down on the chart, with negative noise margins. I also don't know why you got a line filter. Not sure what that would accomplish in your situation. Rick[/QUOTE]
