Helix Antenna – Circularly Polarization GDH1723
Description
Description
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
