DESCRIPTION:
The Bird Technologies 4230-018 7/8 inch RF Line Section is a precision coaxial section designed for insertion into a 50 Ohm RF transmission path between a transmitter and its antenna or load. It features a single socket that accepts a Bird plug-in element of the desired frequency and power range, enabling accurate sampling of forward and reflected RF power when used with Bird directional elements and power meters.
Constructed as a rigid Thruline® line section, the 4230-018 includes Type N (Female) connectors on both ends, simplifying integration with standard RF cabling without the need for separate connector parts. With a nominal characteristic impedance of 50 Ohm, this line section maintains signal integrity while providing access to RF energy through the element socket.
Typical applications include transmitter testing, antenna system verification, RF system calibration, and diagnosticsin communications, broadcast, and industrial RF environments. Users select the appropriate Bird plug-in element and, if required, matching Quick Change connectors or directional sampling elements to complete the measurement setup.
Typical Use Suitability:
Ideal for directional RF power sampling in setups where a plug-in element is used to derive forward and reflected power information — such as transmitter output verification, system tuning, and performance monitoring.
