Abstract (en)
[origin: EP0387445A2] An azimuthal omnidirectional communications mast-mounted antenna in which the monopole antenna (A) is encased in a dielectric cylinder (H) which is received in a conductive base cylinder (B), having a plurality of metallic conductive guy wires (G) of appropriate length, in turn extended by rope guy wires for support of the mast structure (M), and disposed about and radially depending at an acute angle from the outer surface of the base cylinder to form not only guying functions, but simultaneously to serve as an elevated radial ground plane for the antenna.
