Sophisticated Helix Antenna Design,with matching Coax to 50 Ω

CM Helix, SatNOGS, v4, CM Frequency: 434 MHz, CM Wavelength: 691 mm, CM c=299792458 m/s, CM Radius = 110 mm, CM Turns: 8

Reflector Loop Dia: 10.66" The reflector is positioned 0.375" ahead of the start point of the first helix turn, first 4 Turns: 10.32", Next 7 Turns: 8.68", Last 12 Turns: 8.40

The axial-mode helix antenna, first described by Kraus in 1947, is probably the most widely used circularly-polarized antenna, either in space or on the ground
