You know it might be easier to point an OTA UHF yagi at Buffalo and get COZI on 56.1. It comes in here on and off with a CM 4221 on the roof.
Whereabouts are you? I am in North York. With a Winegard flying arrow/ CM 7777 pre-amp / CM rotor mounted on my chimney and I think I got COZI twice this summer for about 10 minutes. CBS/ABC/FOX come in at 98% (Sony Bravia meter doesn't reach 100%). NBC is my most troublesome Buffalo station that usually comes in at 65-71%. On good troop nights I frequently get Rochester's WXXI (PBS) & WROC (CBS) if I turn the antenna. I get ION about 60% of the time from Batavia NY. I was considering changing the antenna out with a 91XG to pull in ION and NBC better. But, I may not have time to before winter. The existing antenna system is a b*tch to take down and was only installed about 4 years ago. I paid a fortune to have an installer put it up in winter.
If you check the WBXZ website their have repairs to do on their transmitter. But, this has been months month. I'm surprised you can get this.
