70 cm antenna on 8 meter boom measurements.

The antenna is tested with HP8753ES calibrated at the cables end. In this way we can get the right characteristic of the antenna without the influence of the cable. A long cable masks the characteristics, which is a problem because we do not have the exact characteristics of the antenna when measuring. In conclusion, we always calibrate at the cable end and test each antenna before sending. Therefore, we can always guarantee best possible antenna characteristics after assembling.
