DatasheetMulti-band Satcom, Communication & GPS Antenna
240 to 400 MHz, 30 to 512 MHz & L1/L2 GPS
SKU: 21-50-82
The 21-50-82 is a rugged multifunction VHF/UHF Satcom and GPS antenna designed for airborne applications. A high strength vertical shell houses 30 - 512MHz linear elements that can be used for V/UHF line of sight “LOS” communications or UHF Satcom at low angles of elevation. An active GPS element, DC powered through the coaxial connector provides circular polarization for both L1 & L2 frequency bands. This vertical shell also supports a pair of horizontal elements containing crossed dipoles connected to provide high angle, circularly polarized UHF Satcom coverage.
