Description

A general purpose omnidirectional blade acceptable to a variety of aircraft applications. Uniquely designed to withstand severe environments and high side-loading situations as experienced on Mach speed aircraft. The simple design allows the frequency range of applications from 700 to 1300 MHz for PN AOCSMA-1 and 650 to 1200 MHz for PN AO6501220-2. The elevation pattern is similar to a quarterwave monopole above a ground plane.
