435MHz 12 turn Helix Antenna
This 50 ohm impedance antenna, when powered with 25-100W of RF in SSB, joins the Molniya orbiting satellites as AO-40 and AO-10
A Helix antenna for 2 metre satellite
The main boom is 25 mm. sq. galvanized steel tube with a 1.6 mm. wall thickness, and 5m. long. This is for a 10 turn helix, and allowing approx 400mm
A Home made Helical antenna for a GPS
In the practical construction of a half-turn quadrifilar helix it is especially important to respect the exact lengths of the helical wires
