435 MHz 9-turn helix
A antennas at G4HLX for AO-40 mode

L'antenne Quadrifilar
The antenna is made up of 2 loops at 90 ° making a 90 ° rotation in the vertical plane,the polarization is circular,right circular if the turns rotate counterclockwise and Conversely

Lindenblad antenna 2m/70cm
the 70cm radiator is changed to coaxial antenna design. Coax cable is routed through the bottom ¼ lambda element, thus no balun is needed – the sleeve is actually the balun

A Sky TV Dish to 60 cm for AO-40 S-Band
Of eight helices long and short I've made in this manner, all have presented VSWR's 1.2:1 or under with no adjustment

Minhas aventuras via satellite
More than 20 years ago, it was much more interesting and enjoyable to do qso via satellite than today. It had no Internet and no cheap PC computers
