COMBINATION LINEARLY POLARIZED AND QUADRIFILAR ANTENNA

摘要

A combination linearly polarized antenna and quadrifilar helix antenna (40) includes a quadrifilar antenna (49) having a first coaxial cable (46) and an antenna with linear polarization (44) external to the quadrifilar antenna and having a second coaxial cable (42). A center conductor of the second coaxial cable is isolated from a center conductor of the first coaxial cable and the first coaxial cable runs substantially concentrically through the antenna with linear polarization.
