432 MHZ EME QRP
the 4.9m dish has being used which is equivalent in gain to four yagis current feed is a two element quad in horizontal polarity

The 9 elements allowed a gain of 12.4dBd 14.55 dBi and was enough to make QSO with the big guns

EME Polarization Rotatione 432MHz Array
At the present time, the best solution for yagis at 432MHz is to mechanically rotate the whole array on its polarization axis
EME 1296MHz
in 1982, i started building my first 2.4m dish for eme, and with a lot of help fi made my first eme qso with k2uyh with 150 watts cw

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
