I'd go with John's prognosis as well as whatever you can glean from Peter's file(s).
Attached are a culmination of some quick scans using various ULX-D and UHF-R kits over the course of a couple of shows. Here in Center City Philadelphia, I have the most success with the upper and lower bands of UHF-R - G1, J5, L3. H4 is unusable beyond a few stories above street level, and J5 is close behind, in my experience. Outdoors or above the "treeline", where other buildings aren't shielding you as well, everything shoots up by, well, a good bit (red overlay).
It's not NYC by any means, but it definitely pays to have varied inventory available to pull from when you have to squeeze in channels.
I really wish I could do full-spectrum scans in situ, but I'm not at that point yet...all things in time.
