MHz Helical Antenna
I decided to build a pair of helical antennas, one for each circular sense. Helical antennas have broad bandwidth, loose construction tolerances, and for 900 MHz, wouldn't be too big

New Helix Antenna Design
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
