Product Details

The ECF-12K is a 12 pF capacitance fixture used for system checks and the calibration of active monopole antennas. This fixture simulates the self capacitance of the monopole rod and is used in place of the actual element.

With recent changes to our Active monopole antenna (converting the input connection from a BNC to a more rugged ΒΌ-20 input) our element diameter changed to 6.17mm (Average). It is our recommendation to use a 12 pF for the ECSM fixture as per ANSI C63.5:2017 and CISPR 16-1-6:2017 The formula for calculating the capacitance is (per ANSI C63.5:2017 and CISPR 16-1-6:2017):

Monopole self capacitance formula

Other fixtures are available as an option.

NOTE: MIL-STD 461F prohibits the use of other types of calibration networks or voltage dividing fixtures. Stray capacitance may exist in such fixtures. The ECF-12K is designed to work with the recent ANSI C63.5:2017 and CISPR 16-1-6:2017 standards and can be used to perform MIL-STD 461G antenna performance verification.
