2 meter and 70 cm Dual Band Yagi Antenna PA144-432-34-6-2CBGP Dipoles and two “N” connectors view. 144-145MHz and 432-434MHz.
Tropo – EME with stack of two or four antennas.
100 W will be enough to start work a lots of amateur around the world on two bands.
System with just two vertically stacked antennas (2.55m distance) could achieve about 17.35 dBi on 144 MHz and about 20.8 dBi on 432 MHz.
Save your space for another antennas.
