Foldable UHF Satcom Antenna

The 20-30-10 series are combined Hi-Lo angle UHF Satcom Antenna designed for installation on a vehicle roof, shelter or housing via either a fixed or magnetic base. The 21-30-10 series has 4 spring loaded elements which can be easily and immediately deployed.

The antennas consist of two co-located elements; a circularly polarized cross-dipole and a linearly polarized broadband monopole. The two elements have separate RF feeds, and by manual selection of either, full hemispheric pattern coverage is provided. The Lo angle mode is intended for elevation angles up to about 45° and the Hi angle for approximately 45° to zenith. Optimum function is achieved when the surface upon which the antenna is mounted acts as an effective ground plane.

Construction is from rugged fiberglass, foam-filled for structural integrity and prevention of moisture ingress with aluminum alloy dipole elements and base housing. The 20-30-10 series of antennas offer best in class performance, combined with portability and fast deployment time. Lightweight and compact, they are ideal for special mission applications.
