The Conical Monopole Antenna

Abstract

An antenna of the monopole type has been produced which provides a VSWR of 2.5 to 1 relative to 70 ohms over a 6.3 to 1 bandwidth. The peak amplitude of the radiation pattern in the vertical plane lies along the ground plane over a 4 to 1 frequency range. The electrical length of the antenna is 0.16 wavelengths at the lowest frequency, and, since the central supporting member is conductive from the ground to the top, obstruction lights or other small objects may be mounted atop the antenna without disturbing its characteristics.
