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 quantities 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.
This meter requires optional plug-in elements to work, use the tables below to identify your required part numbers then contact us for a quote.

43, General Purpose Wattmeter - The Industry Standard
A field-proven portable, insertion-type instrument designed to measure both forward and reflected CW power in coaxial transmission lines under any load condition. With a full-scale accuracy of ± 5%, it accurately measures RF power with low added VSWR and insertion loss. QC (quick change) type connectors and a full range of plug-in elements provide a wide choice of frequency ranges and power levels giving the Model 43 amazing flexibility. Two extra elements can be stored in the housing, one on each side. The Model 43 is easy to use and simple to service in the field.- Accurate CW field power measurement over 450 kHz to 2.7 GHz and 100 mW to 10 KW.
- Uses industry standard Bird elements with space to store 2 additional within the meter housing
- Rugged metal housing for the most demanding environments
- Quick Change (QC) connectors to minimize the need for adaptors when making critical measurements
