They worked on the original radios that had the single rectangular patch
antenna. I think they worked on the 450 if it was in the original case.

A field tech replaced a Cambium 450 SM today and said it had a WB "focus
ring" on it. I had totally forgotten about those. He dutifully put it on
the replacement SM.
I thought those were only for FSK radios, or did they supposedly work on
subsequent versions like 430 and 450?
