Helix Antenna – Circularly Polarization GDH1723

Applications

  • RMK-34
  • AS-3686/A

The helix antenna is constructed on a filament wound epoxy cylinder incorporating the matching section within the base.  A right hand helix transmits and receives right hand circular polarization.  This type antenna can be readily scaled to other frequencies with left or right polarization.

U B PN GDH1723 = Right-Hand Circular Polarized

U B PN GDH1723L = Left-Hand Circular Polarized
