2 Meter antenna cycloid dipole
The 6 and 2 meter cycloid dipoles, note the rain shield covering the rear portion of the matching sections along with the 1/2 wave coaxial cable delay line comprising the 200 ohm balun on each antenna
Yagi LFA 9 elementi per i 2 metri
Yagi lfa loop fed array per i 2m, con boom da 4.6m. l'antenna e' composta da elementi direttori e riflettori come le normali yagi
Matching transformers for 3 stacked yagi
Using three antennas often provides a good compromise between increased antenna gain
