Not sure if people know about the HeyWhatsThat website?
Basically, you enter your location, in Latitude and Longitude (I use Streetmap UK to get the Lat/Long for any particular location in the UK) give your panorama a title and set a height above ground for your antenna and the program plots the visual horizon for your location from that height.
For VHF/UHF RF, you can usually say that the signal will get further than visual horizon, but it's a good indication of 'good' and 'poor' areas from any given spot.
The URL for the website is at HeyWhatsThat

Brilliant tool, I have used it for acquiring geographical scatter points such as large objects and successfully working backscatter on 50 and 70MHz - Talk about bending radio waves around corners!

The option to see hills might also offer a view to knife edge refraction as well...
