• Second socket is for more sensitive element to measure reflected power and accurately determine VSWR
• Dual meter configuration simultaneously displays forward and reflected power

The Bird 4526 is an RF wattmeter with two meters and two element sockets, simultaneously displaying forward and reflected power. The second element socket enables the use of a more sensitive element to measure reflected power and accurately determine VSWR.

The Bird 4526 is designed for power measurement in CW and FM systems which employ 50-Ohm cable or 7/8" EIA transmission lines. The rack panel fits standard 19-inch equipment racks and uses the same elements as the Bird Model 43 Wattmeter. Please note, elements are sold separately and can be ordered from the accessories section of this page.

The Bird 4526 is compatible with a large number of elements, covering a wide range of frequency and power ratings.

Compatible elements can be viewed by clicking here and viewing tables 1, 2, 3, 4, 6, 13, and 14.

**Please note, elements are sold separately.**

All Bird plug-in elements are calibrated in accordance with meticulous Bird calibration procedures supported by a long history of mean deviation values to assure adherence to advertised specifications of current instruments, as well as field interchangeability with equipment purchased, used, and trusted in all the years since its introduction.

Bird offers several versions of its panel mount RF Wattmeter. The chart below provides an overview of the main features of each. Please note, frequency and power are dependent on the elements being used.
