Homebrew Arrow Satellite Antenna
The Arrow Antenna is a design classic: it combines light weight, compact design and functionality in a single package for operating FM dual band satellitesoom
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
2.4 m offset dish
From 1296 MHz up to 24 GHz with excellent RX performance,i will use that antenna temporary on low bands too

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
