Bird 43N Watt/SWR Meter Field Insturment Test Equipment

General Purpose Wattmeter
The Industry Standard - Birds Famous General Purpose Wattmeter
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

The Bird Model 43 THRULINE® directional wattmeter is a portable insertion-type instrument for measuring forward and reflected power in coaxial transmission lines. It will accurately measure RF power under any load condition. Plug-in elements are available to fit your frequency and power needs..

The plug-in elements (slugs) determine the power rating and frequency range of the Bird 43 wattmeter.

This meter is in good working order and the cosmetics are typical of a used field instrument. The handle shows wear but it will be good enough if the meter is used on your desktop.
