I have both. I have found the ST2 to perform (receive) better than the discone, especially at the lower end. I purchased mine through Solid Signal for $35. It came with the 75 to 50 ohm adapter and 50' of coax. I would purchase it again, and probably will for my camping trailer.
I should note that that I compared the two antennas simultaneously. Both are 35' AGL. I used different radios and the Scantenna 2 always won. Even just last night I was picking up a weak signal, and compared them again. Another helper I use is a Combination Notch/High pass filter - HPN-30118. I have FM and AM BCB killing me at my location. With this filter I now hear transmissions I previously did not.
Transceivers, filters and antennas. Having fun in the sun.
