Strictly as a guess, I would try
HRO Woodbridge . I wouldn't turn my nose up at a dual bander HT antenna, either. I have an old MFJ model that works quite well on my 245, and works acceptably on 800 to boot.
I can't say that my UHF reception on the 396 is bad - I have programmed it for several freqs when I travel to NJ, and have no problems hearing what I want, using an Austin Spectra on my car. I can usually hear the BWI 400 mhz systems with no problem, although it's an unfair test - I'm 15 minutes from them.
