From larger to smaller

UHF Connector

Male PL-259 mates with Female SO-239

"The PL-259 connector mates with the female SO-239 connector. The PL-259 connector is usually on the coax and the female SO-239 is on the radio."

BNC Connector

Wiki: BNC Connector:

"The BNC (bayonet Neill-Concelman) connector is a type of RF connector used for terminating coaxial cable."

The BNC connector (initialism of "Bayonet Neill–Concelman") is a miniature quick connect/disconnect radio frequency connector used for coaxial cable.
