DatasheetUHF Satcom Antenna
225 to 400 MHz
SKU: 21-30-29M
The 21-30-29M is a magnetic mounted combined Hi-Lo angle UHF Satcom Antennas designed for installation on military vehicle roof, shelter or housing. The 21-30-29M has the coaxial connectors mounted on the side of the antenna base.
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.
Construction is from rugged fiber glass, foam-filled for structural integrity and prevention of moisture ingress with aluminum alloy dipole elements and base housing.
