ZA-1450 UHF DF ANTENNA ARRAY<br />
The DRS ZA-1450 Ultra High Frequency (UHF) Direction<br />
Finding (DF) Antenna Array provides for DF measurement<br />
of signals in the 500 to 3,000 megahertz frequency band.<br />
The DF antenna array is designed for airborne operation<br />
when mounted to the bottom of an aircraft fuselage, or for<br />
ground-mobile operation on the top of a vehicle or<br />
equipment shelter.<br />
The DF antenna array is enclosed in an airborne-qualified<br />
radome containing two Adcock-type sub-arrays, each<br />
consisting of five passive folded dipole antenna elements<br />
symmetrically arranged in a pentagon. The lower–band array<br />
covers the frequency range from 500 to 1,000 megahertz,<br />
and the upper–band array covers the frequency range from<br />
1,000 to 3,000 megahertz.<br />
ZA-1450 DF Antenna Array Interior<br />
The ZA-1450 DF antenna array is used with any of DRS’s<br />
range of high performance wideband Very High<br />
Frequency/Ultra High Frequency (VHF/UHF) intercept and<br />
DF systems, to provide high accuracy, high sensitivity<br />
DF measurements.<br />
