553-75, 75-150 MHz Coupler Element

553-75, Coupler Element is used for RF sampling. The wattmeter does not read when these elements are installed, but simply serves as a line section.

Bird cannot guarantee that the reading error will not exceed ±5% of full scale unless the element is calibrated in the proper wattmeter.
