This 50 ohm impedance antenna allows, when powered with 25-100W of RF in SSB, to reach satellites with Molniya orbit like AO-40 and AO-10
Helical Feed Antennas
Helical antennas have long been popular in applications from VHF to microwaves requiring circular polarization, since they have the unique property of naturally providing circularly polarized radiation
