I'm trying to figure out the simplest setup I can use to receive all of the channels along the 300 and 200 degree radials in the linked report.
My house is on a hill and I can get the UHF DTV channels down to 21 dB NM with any of three simple near-TV antennas. Everything I want is true LOS.
I cannot get my set to receive any VHF channels, off of either of two rabbit-ears, and I'd particularly like to get Ch 7 and Ch 9 on the 300 degree radial. Since the link margins are so high, I suspect that my TV might not even attempt to get DTV on those older channels - I cannot find any info to prove this one way or another. I seem to remember the original DTV plan was to move all channels to UHF. (???) Can anyone confirm that a Sony Bravia KDL-26M4000 can demodulate the digital signals in VHF?
At any rate, I'd like to get a setup in the attic (we get tremendous wind and ice storms here on the prairie) that gets reliable signals in all weathers. If possible, I'd like to get UHF from both Colorado Springs and Denver - a 100 degree spread. I'd also like to get VHF down to channel 7 on the 300 degree radial (Denver.)
My attic space is somewhat limited due to vaulted ceilings, but I think I can fit two 8-bay UHF antennas, and surely two 4-bay antennas.
Is this the cheapest setup for my UHF goals? Do I need an active coupler for these two antennas? Should I use two LNAs and a standard coupler? How best do I couple them and how far apart do they need to be?
I guess I'd need a third antenna for VHF on the 300 degree radial. Those noise margins are 50 dB, so it should not take much. How do I couple that in?
Thanks for your help.
