HB9CV, horizontal pattern, 0dB = 4,17dBd |
HB9CV, vertical pattern, 0dB = 4,17dBd |
From the coax-socket goes a capacitor to the point X, here 15pF (try out for best SWR) The phasing line is made of 2mm brass wire and has a distance of 5mm to the elements (uncritical).

The picture shows the construction of a 2m- HB9CV-Beam better than a long description. Here you see the details of the 2m-HB9CV with the point X, the C=15pF and the coax socket. The phasing line is fixed with 5mm distance to the boom.
