QUADRIFILAR HELIX ANTENNA
SQFH-4065 400-410 MHz 5 dBi. Gain


Quadrifilar Helix Antenna for Weather Satellite Atmospheric Research purpose provides horizon to horizon coverage.

Quadrifilar Helix Antenna uses a self facing design and is a full wave Helix for perfect RHCP/LHCP, circularly polarized and enclosed in a Fiberglass Radome, suitable for a Pole-Mount.

The Helix uses copper tubing for filar windings and the low VSWR below 1:1.5 provide perfect matching and increased antenna efficiency with the peak gain of 5 dBi.

Filars are held symetrical to the vertical axis to maintain purity of the radiation.

This antenna has been supplied to "EuroLinX a division of Videohouse nv | Media Facilities | Belgium"
