S04D101-D4 is a light weight, low profile, low drag blade antenna, designed for telemetry and airborne vehicular -instrumentation application in the frequency band of 1430-1550 MHz . Electrical design involves matching circuits coupled to a monopole terminated with a co-axialconnector providing virtually perfect omni-directivity over the full operating range. Shell is vacuum moulded from single-piece glass to provide a rugged and reliable aerodynamic structure for withstanding the extreme environmental conditions experienced on subsonic & supersonic aerodynes. S04D101-D4 is designed to meet military, regulatory and statutory standards.
