Product Details

*** As of Dec-2019 ***

All new active monopole antennas have been re-designed to accept a telescoping rod with a 1/4-20 thread instead of a BNC connector. This new connection makes for a better electrical performance as well as an improved rugged design.

Please note that this new design will not accept the use of the ECF-10 (with the BNC connector) please refer to the new ECF-10K Equivalent capacitance fixture kit that will also inlude a BNC tee and 50 ohm load (all of which is required to preform an antenna systems check).

The ECF-10 is a 10 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.

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-10 is designed per SAE ARP 958 and can be used with MIL-STD 461E & MIL-STD 461F.
