Winegard and Channel Master post useful information on their public websites:

RCA does not choose to share much specifications. http://forum.tvfool.com/showthread.php?t=16650 That leaves one to estimate based on similar designs from other brands which do publish useful data.

You're correct, 2-edge is a term that describes the number of terrain obstructions a signal path has. LOS (line of sight) is ideal, 1-edge means the signal has to refract (bend) over one piece of terrain in order to have a path to the receiving location. Beyond 2-edge the term tropospheric is used because the majority of any signal at the receiving location likely is the result of reflection off of the upper atmosphere's tropospheric layer. Of course, a line of sight path is much preferred for reliable reception... Tropo is quite variable and therefor the least ideal signal path.
