If you look at the towers in my viewing area some rebroadcast the same callsign on different real channels. Example: kjtl, real 15, virt 18, 42 miles and 125 degrees. It is also k32ic, real 32, virt 18, 6 miles and 349 degrees. Again at k20jb, real 20, virt 18, 30 miles and 296 degrees. (K33hg at 225) 33 miles.
When recording some programs from k19aa instead of that programming I get recorded programming from kfdx real 28 also k25jo real 25 both are virt 3. Channel 19 is a PBS rebroadcast from kwet 74 miles and 345 degrees. K25jo has NM(db)31 and k19aa is NM(db)27
All the channels available from the tower 30 miles and 296 degrees show 14.7 – 16.9 NM(db) and with winegard 8200 antenna I have trouble picking up those. A lot of the time just a hit and miss situation.
I'm thinking if I point my antenna to 340 degrees I can pick up the tower with k19aa, also tower with k32ic, and the tower with k30jp 46 miles away. Those three towers are 333 to 353 degrees. I know the tower 46 miles show NM(db) -7 to -10. Those same channels on the tower 30 miles and 296 degrees with positive NM(db) are a sometimes available. I might still get some signal from 296 degrees with it pointed at 340?
I selected an antenna height of 5 because as I select higher the NM(db) numbers get worse until about 500.
Anyone have suggestions
