K1WHS in the U.S.A. has an array consisting of 48 Yagis which enable him to contact stations with more modest installations. "In 1970 a technician from Stanford University came to Athens because the tracking station they had set up on Mount Pendeli could not pick the University's satellite, whereas they were getting good signals from it in Spain.
The two down-link 8 element yagis are each fitted with a small D.C. motor directly coupled to a 9 inch length of M5 brass studding rotating inside a block of PTFE linked to a push rod which can move the antennas 75 degrees both sides of the vertical position, either in unison or in opposite directions.
This type of propagation occurs during certain special meteorological conditions, like high barometric pressure and extreme heat. We sometimes hear stations in Malta and Sicily with very loud signals." "In 1966 I built an aerial array consisting of 8 nine-element Yagis for 2 metres with the axis of rotation pointing to the North Star enabling me to track the Moon automatically.
