so-239 to N-Type adaptor

Nickel Plated with Teflon Insulator

This is the type of adapter you need if your radio or scanner has an N-type socket but you have a PL-259 on your antenna cable.

This female UHF SO-239 connector adapts your pl-259 coax plug to an N male.  
some Dual Band or scanner aerials use an N-type connector
