Antennas have been designed and kalkulated by DJ 9 BV

The antennas are optimised high gain long jaghi`s, the one I built is a 12 element with a boom length of about 6 meters. The radiating element is a folded dipole with a transmissionline balun made of RG 142 to handel power up to 1KW. The whole system is vertical stocked to 3.90 meters apart from boom to boom.

In case of interest, contackt me and I will send you the construktion plans or put
