40m4-HQL-12 - a new highly efficient four-element antenna on a 12m boom. Elements shortening with almost zero loss thanks to special coils with high quality. The antenna used the active feeding of two elements using the phasing line. As a result of this feeding, the gain and ratio F / B in the band 7.0-7.3 remain very stable. The SWR in this band does not exceed 1.3 (1.5 at 7300!)
