Dual Spiral Antenna Model 8503661
Overview
Model 8503661 is an integrated antenna assembly consisting of a pair of planar spiral antennas of opposing (left- and right-hand) polarization with an integrated high-speed switch and radome assembly. The output of the assembly is either the left- or right-hand polarized aperture, as determined by the RF switch setting. The RF switch is controlled via the application of a DC bias to the coaxial center pin. No other control circuits are required for operation of the 8503661. The 8503661 has been designed and qualified for the military airborne environment, and for most applications—including supersonic flight—it does not require any additional aerodynamic protection.
