| 摘要 |
This invention comprises an antenna array of collinear, end-fed dipoles spaced substantially less than one-quarter wavelength from the reflector. Consecutive dipoles are energized through phasing loops with the end dipole energized by a coaxial feeder or by one of the two output ports of a balun. A radome with a helically wound resistance heating wire is used to protect the array from the elements. Means comprising the addition of small auxiliary radiators at one of the ends of each dipoles are provided to reduce radiation polarized perpendicular to the axis of the array.
