Bird Electronic Corporation 43P Wattmeter, Thruline
The Bird 43P Wattmeter is a portable, self-contained RF wattmeter designed for field and laboratory use. It is part of Bird Electronic Corporation's 43 Series and features the same reliable, field-proven design as the standard Model 43, but with the addition of a built-in peak reading circuit. This allows for both average and peak power measurements, making it suitable for applications involving modulated signals such as AM, SSB, and TV. The 43P covers a frequency range of 450 kHz to 2.7 GHz (depending on the element used) and can measure power levels from 100 mW to 10 kW. It is compatible with Bird's standard plug-in elements, ensuring flexibility for various frequency and power ranges. The rugged construction and portability make it ideal for installation, maintenance, and repair of RF transmission systems.
