Antenna elevator system for amateur satellites
The actuator is a cheap and heavy tool with high enough torque, ideal for elevation systems, but in practice it needs quite an effort in order to operate correctly in your homebrew antenna system
Antenna Turnstile per i satelliti Polari
due spezzoni di cavo 75 ohm la cui lunghezza deve differire esattamente di un quarto d'onda della frequenza di 136-137 MHz
Antenna quadrifilare per la ricezione dei satelliti meteo polari
L'antenna puo' venir corredata da due riflettori incrociati.E' consigliato un preamplificatore in prossimita' dell'antenna
A Portable Antenna for Mode B and J Satellites
In my case, I had been working SO-35 with a 1/2 wave on 70cm and a 1/4 or 5/8 wave on 2m. With these antennas and a little planning, it is possible to work this bird from a train
