Continuous Wave

RF Wattmeters, Plug-In Elements and Rigid RF Line Sections

Bird® offers a wide selection of portable insertion-type instruments for measuring forward and reflected power in coaxial transmission lines. Thruline instruments can be left in the line for continuous monitoring of either the transmitter power output or the amount reflected by the antenna.

These two qualities are actually the most important transmission parameters: Tuning for the minimum reflected power results in a good match of the load (antenna) to the line, and adjusting the transmitter for maximum forward power into a matched antenna approaches ideal design goals, These optimum system adjustments result in a low Voltage Standing Wave Ratio.

Bird’s plug-in elements ensure precise, frequency-specific calibration for traditional wattmeters. Trusted for years, they’re perfect for users seeking fine-tuned, reliable performance.

Quickly and easily install Bird RF Line Sections between your transmitter and antenna or load for precise power measurements and efficient system performance.
