  The Bird Model 43 THRULINE┬« Directional Wattmeter is 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 Bird Model 43 amazing flexibility. Two extra elements can be stored in the housing, one on each side. The Bird Model 43 is easy to use and simple to service in the field.

   The 43 is an insertion-type RF wattmeter, designed to measure RF power and load match in 50 ohm coaxial transmission lines. It is intended for use with CW, AM, FM, and TV modulation, but not pulse modulation. When used in 50 ohm applications, the 43 has a maximum VSWR of 1.05 for frequencies up to 21 MHz. The meter provides direct readings in watts with an expanded scale for easy reading. The scale is graduated for 25, 50, and 100 full scale. Elements are available in a variety of power and frequency ranges (see the Bird Electronic Corporation Catalog for details).
