Appendix A: Calibration Certificate

Extended Dipole Calibrations
Referring to KDB865664 D01, if dipoles are verified in return loss (<-20dB, within 20% of prior calibration),
and in impedance (within 5 ohm of prior calibration), the annual calibration is not necessary and the
calibration interval can be extended.

The return loss is <-20dB, within 20% of prior calibration; the impedance is within 5ohm of prior calibration.
Therefore the verification result should support extended calibration.
