This compact, lightweight bent stub antenna was developed for airborne beacon transponder applications. The vehicle skin acts as the antenna’s ground plane and can be mounted through a D-hole to a .25″ thick surface and secured with supplied lockwasher and nut. When not directly mounted onto a metal surface, a 2-inch diameter ground plane is needed.
