First introduced in 1963 the JIB Monopole antenna is a workhorse of Astro's deployable antenna product line. With more than 1000 units deployed on-orbit it has proven itself to be a robust and 100% reliable solution for multiple applications; from the Gemini and Apollo manned space programs through the current GPS constellation utilized in numerous configurations, the JIB Monopole has worked every time.
