Hello, I'm new to TV Fool and have found this site and the tools to be fantanstic. Thanks for all your expert help.

My Location:
NW Tucson, AZ
My problem:
I've been receiving OTA all the major networks and Tucson channels for years with a good sized VHF/UHF antenna in my attic. The only problem in NW Tucson is that we are shadowed to the transmitters on Mt Bigelow to the east where most of the major network transmitters are located. Because of this ABC, NBC and CBS have rebroadcasting translators to the south of Tucson. The problem is FOX, channel 11 does not have an alternate transmitter. Years ago before digital I could pick up Ch 11 with a rooftop antenna, cut for VHF 11, and a preamp. But the preamp is long gone and Ch 11 now broadcasts on RF 25. I still have a decent UHF antenna on the roof but can't get Ch 11 on 25, especially without a preamp. I thought I would give Phoenix a try and pointed my rooftop UHF towards Phoenix. It is a straight shot 90 miles up I10 to south mountain without any noticeable obstructions. I did a scan and wow! I picked up about 15 Phoenix stations including FOX Ch 10. (BTW, FOX 10 broadcasts on RF 10 but I found it on 10.2 RF 26, not listed on my TV Fool report, but found here

I thought all was good until I went to watch the superbowl on FOX and found all the Phoenix channels GONE! I messed around with the antenna, cabling, connections, direction, etc. all to no avail. Later I discovered all the channels come in fine late at night and in the morning and disappear around 11am. From what I have read this may be due to some tropospheric conditions that change as the desert heats up during the day. I'm thinking a better antenna or preamp may be needed to boost the gain enough to get past these conditions. Is there a better antenna that you believe could help? Preferrably without a preamp. Or other suggestions? I don't believe I need VHF since I can get Ch 10 on RF26.
My current rooftop UHF is a 30 year old, maybe winegard, at 21 ft.
