I think he has tried that, so the only other thing to try is something like a bowtie array without a reflecting screen. I've pointed out a site that has design details (
http://m4antenna.eastmasonvilleweather.com/index.html) in other threads. My concern in this situation is having enough gain for RF 9 (Fox 10.1). I'd suggest putting a prototype together to test before going all out.
Another idea would be getting a VHF-only antenna for RF 9 and combine it with a USVJ. This would work only if you can make all the other channels work at the same time.
