Donno about UHF radials but I've fabricated my own for the VHF Stationmasters. If you are unable to locate the desired fitting you may be able to use a UHF double female barrel adaptor on the UHF male at the antenna and then use a UG-83 adaptor (which is a UHF male to type N female). I personally don't like the idea of double adaptors but should work in a pinch.

Sad times, indeed. First of all no one there could identify the connector/adapter part. Second of all, they claim "no spare parts available" for Stationmaster antennas. I even tried to buy a set of radials for a PD455 that has lost them, and they don't even offer them separately! Anyone have a bad UHF Super StationMaster that they want to sell off the radials or coaxial connector/adapter from? To top matters, the antennas aren't even built in the states anymore, and are contracted out to a non-RFS company. One more nail in our industrial coffin! One another note - has anyone run a PD455 with and without the radials, and noted the difference in performance?
