Q159 Series Spiral Antenna

The Q159 Series antennas are amplitude tracked on a 100% basis versus factory standards, ensuring interchangeability at the system level. In addition, the axial ratio is extremely low (considering the low frequency cutoff versus the nominal 2” diameter of the antenna) over the majority of a hemisphere. Together, these characteristics make the Q159 Series of antennas an ideal element for array and DF applications.
