Three antenna were trialled, a 600mm G3RUH dish, a flatter 600mm dish of about .5 F/D and a commercial 640mm off-set satellite dish. For the G3RUH dish and the off-set unit

The Eggbeater Antenna
The antenna is made of two full waves loops, mounted at right angles to each other
The Lindenblad antenna
the Lindenblad antenna consists of four half wave folded dipoles slanted 30 degrees to the horizon, oriented 90 degrees to each other in azimuth, spaced 0.3 wavelength apart
The Quadrifilar Helix Receiving Weather Satellite
Types of Coax
you are going to need some coax to run to your antennas. we will talk about coax
UHF Yagi 10 element for AO-40
successful communication via "AO-40" by using the UHF UpLink, a Power of 150-200 Watts ERP was necessary ERP is a combination of Rig power output, Coaxial loss, and antenna gain
