I bought an Ancor male plug for connecting the antenna cable to the VHF radio. The plug was made for my cable size (RG58) and it fit the threads on the back of the radio. Later, I realized it is a UHF plug. I tested it on my driveway. The weather station comes in loud and clear. Will a UHF plug work properly on a VHF radio? What is the difference between a UHF plug and a VHF plug?

Yes, it will work. UHF specific connectors are designed for less signal loss at higher (ultra) frequencies. Since VHF is lower frequency than UHF, you'll be OK. BillS

When the designator "UHF Series" was applied to these connectors it was way back in the 1940's. No serious UHF work is done with the the "UHF Series" connector now, and most people do not use them at frequencies above 30-MHz because of the impedance discontinuity which they represent. They are not really a true 50-ohm connector.

However, all that water under the bridge, they are widely used in VHF mobile radio service due to the rather rugged nature of the connector.

There is no "VHF series" connector. The designator "UHF series" is just a historical anachronism.
