I purchased two UHF stubby duck antennas and a UHF 1/4 wave whip at the Shelby hamfest last month. After seeing a lot of 400-420 and 450-512 radios equipment on ebay, the question is, "Can you determine the resonant freq of such antennas by mounting them on a ground plane and measuring the SWR?" Since they are used on a ground plane, is this a realistic test?

What frequency are you trying to monitor from 40 miles away? Depending on whether is VHF, UHF, or 800 will make a difference in what you need. The terrain between you and the transmitter will also make a difference.
