Moonbounce Station
Building equipment for various frequencies ong distance contacts, especially on vhf, uhf & shf
Moon Tracking System without PC
pstrotator supports separate antenna rotator controllers for azimuth and elevation control. it can control two separate rotor interfaces
Mike maintains a amateur satellite page
satellites are fun and easy to work. here i am on lake erie working the a0-27 satellite running just 2 watts
432 mhz low noise preamplifier for moonbounce
432 MHz Low Noise Preamplifier for Moonbounce Operation and Weak Signal Reception
Parabolique Decalee de 80cm Modifiee pour la Rx a 2.4GHz
this 50 ohm impedance antenna allows, when connected to a preamplifier and a 2.4ghz "downconverter", to receive 2.4ghz transponder amateur radio satellites like ao-40

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
