After a hard work I finally installed the new antenna system that is a bay of 4 X 8 elements EF0208 of Pope YU7EF. I used a split dipole followed by a coaxial 1/4 wave choke. To couple the bay I used a fourth wave line matching transformer made of RG-213 foam to match the 25 ohms of two pairs of antennas into 50 ohm. The system is more sensitive than the previous one. The distant beacon signals and EME stations are improved as well as noise figure. Now listening stations with 2 antennas is easier waiting for the first QSO!
