A Coaxial adapter is a single-piece component allowing the connection of two different pieces of equipment that cannot be joined directly

What does a Coaxial Adapter do?

Coaxial adapters provide a convenient method of connecting RF equipment together.

Applications

Test and measurement
Communications
Base stations
GPS
LAN
Antennas

Types

There are two main types of RF coaxial adapters;

In series:

A two-port Interconnection device that provides a convenient method of converting from one gender to another in the same series. Is also known as an inline coupler or inline barrel adapter. An In series coaxial adapter is also a handy way to join two lengths of cable together to extend the run within the same connector series.

Between series:

A two-port interconnection device allowing the conversion between two different types of RF coaxial cable connector types. For example BNC to N, SMA to TNC.
