These antennas are primarily used for aerospace and weather satellite atmospheric research programs and they provide horizon to horizon coverage while tracking a satellite with excellent constant gain even at low slant angles and high noon position.
Quadrifilar Helix Antennas use a self facing full wave helix design for perfect circular polarization. The helix uses copper tubing for filar winding which are held symmetrical to the vertical axis to maintain purity of the radiation. VSWR of below 1:1.5 of this antenna provides perfect matching and increased antenna efficiency with a peak gain of 5 dBi.
These antennas are enclosed in a Fiberglass Radome and they are suitable for a pole-mount.
