Originally I tried putting a UHF antenna on the highest piece of furniture in my bedroom.  Results were pretty terrible, I could get only 4 stations reliably.


Then I moved the antenna outside onto a short mast, just a few feet above the roof line.  This improved things dramatically and I could now get 9 stations.  Better, but still not great.


When I replaced the old VHF antenna on the other side of the house with a much larger and more powerful VHF/UHF antenna, I stacked the old antenna on top of my UHF antenna, and inserted an additional 5 foot segment into the mast.  I pointed the VHF antenna at Lincoln and the UHF antenna towards Council Bluffs.  I could now pick up the 7 VHF stations in Lincoln, while the greater height and slightly altered angle allowed me to pick up and additional 6 UHF stations in Omaha and Iowa, giving me a total of 24 TV stations.


This setup was adequate, though KLKN on the far side of Lincoln just barely came in.  When I built my new computer, I upgraded to a Hauppage dual tuner, which proved to be far less sensitive than my old ATI single tuner.  This made KLKN almost unwatchable, which was a real bother to me because that station is the local RTV affiliate.  So I searched around and ordered the biggest, most powerful VHF antenna I could find, which turned out to be a Winegard YA-1713 high-band VHF antenna.  Since there are no low-band VHF stations (channels 2-6) in the area, a high-band antenna (channels 7-13) made a low more sense.  It finally got (almost) warm enough for me to work outside yesterday.  I also replaced the regular dual-shield coax leads from the antenna to the amplifier with quad-shield and I raised the VHF antenna a couple extra feet, which theoretically should improve the signal even further.  I was also able to refine the direction I was aiming the antennas.  The results aren't quite as dramatic as I'd hoped, but KLKN is coming in completely stable now, which is all I really wanted.

The only nearby stations I'm missing are KFXL, a UHF Fox affiliate in Lincoln, and KYNE, the PBS affiliate in Omaha.  Trying to receive KFXL would require another UHF antenna aimed at Lincoln and a highly complicated series of filters and signal combiners. Since they have only a single subchannel and I already get KPTM, the Omaha Fox affiliate, it's totally not worth the effort and expense.  I'm not sure why I can't receive KYNE; it might be because they have a fairly small tower (117m).  They have a total of 3 subchannels, but since they carry pretty much the same programming as KUON, I'm not really missing anything.

Different affiliates appear to have different schedules. The one here runs Ghostbusters on Saturday morning between Fat Albert and the Archies.

I never really cared for the Filmation version of Ghostbusters. I always preferred DiC's The Real Ghostbusters
