Abstract A foldable antenna for mounting on a base member. A vertical mounting mast includes the base member at one end thereof and a cavity member at the other end. A plurality of rigid radiating elements depend from the cavity member and are threadably secured thereto. A plurality of rigid ground plane members extend from the base member in a plane perpendicular to the mounting mast and are threadably secured thereto. The radiating elements may be designed to transmit and receive circularly polarized waves. Further, the cavity may have a monopole radiating element threadably secured thereto in a plane parallel to the plane of the mounting mast and a second set of ground plane elements operatively associated with the monopole radiating element threadably secured to the cavity in a plane perpendicular to the mast. The radiating elements and the ground plane elements may be removed and transported in a carrying case member which encompasses the mounting mast between the cavity and the base member.
A foldable antenna for mounting on a base member comprising: a vertical mounting mast having said base member at one end thereof and a cavity member at the other end thereof; a plurality of rigid radiating elements depending from said cavity member and being threadably secured thereto; and a plurality of rigid ground plane members extending from said base member in a plane perpendicular to said mounting mast and being threadably secured thereto; said cavity having a monopole radiating element threadably secured thereto in a plane parallel to the plane of said mounting mast and a second set of ground plane elements operatively associated with said monopole radiating element threadably secured to said cavitY in a plane perpendicular to said mast.
