Antennas

In May 2021, the Fritzel FB23-beam, which is shown on one of my latest QSL-cards and which had been doing a good job for over 20 years, was replaced by an Ultrabeam UB20-mx.

The Ultrabeam forms a 2-element moxon yagi on 20m and 17m, and a 3-element full-size yagi on the upper bands (15m to 6m). The lengths of the elements are changed by motors that push copper strips through fiberglass tubes. This achieves a good SWR on all bands. The antenna system also includes a matched inverted vee for the bands from 160m to 30m and a yagi for VHF and UHF.

The Ultrabeam and the VHF / UHF-yagi can be rotated.
