4304A, Range Switching Broadband RF Wattmeter
4304A
Range Switching Broadband RF Wattmeter
RF Power Measurement with Built-In Range Switching
The Bird 4304A simplifies RF power measurement by combining the trusted mechanical design of the Model 43 with a broadband plug-in element and a 5-position range switch. It’s built for technicians who want to cover a wide frequency range without carrying a full case of elements. With support for CW, AM, FM, and TV modulation, the 4304A is a durable, portable solution for everyday RF power monitoring from 25 to 1000 MHz.
Why Choose the 4304A?
One Element, Five Power Ranges
The pre-installed 4304-1 broadband element and front-mounted range switch let you measure multiple power levels without changing slugs.
Covers 25 to 1000 MHz
Suitable for most general-purpose RF systems, including broadcast, LMR, and telecom.
Rugged and Portable
Shock-mounted meter, aluminum housing, and quick-change connectors make it ready for field use.
How It Works
The 4304A uses a built-in broadband plug-in element to sample RF energy from a 50-ohm coaxial line. A directional coupler senses forward and reflected power, while the analog meter displays the result. The 5-position range switch lets you scale full-scale readings from low to high power without physically swapping elements simplifying setup and minimizing handling.
