Our
F-15 ALR Quandrant Warning antenna suite is a combat proven
high quality aviation standard. These DF antennas were designed
for the AN/ALR-56 Threat Analyzer RWR system onboard the F-15
Eagle jet fighter. The Wing Tip and Fin Cap assemblies contain
Randtron Antenna
Systems' RS-2
antennas, incorporating two inch Archimedean spirals. The RS-2
spirals are smaller per wavelength than competitive designs,
allowing for the placement of the antenna closer to the radome.
As a result, the shorter reflection path improves the antenna
bandwidth.
A second innovation incorporated into this assembly was use
of a thin skin syntactic-cored radome. The syntactic core features
a very low dielectric constant combined with excellent structural
properties.The molded construction process results in homogenous
parts with outstanding part-to-part consistency. In recent production
buys, the F-15 DF system has been upgraded to dual polarization
capabilitities on the F-15I with our 2
inch sinuous antennas. Randtron
