The MONOPOLE antenna has the shape of two inverted cones of metallic conductors placed on a conducting ground plane.
This radiating volume is supported by a central tower guy with insulated cables.
This antenna assembly is isolated from the ground plane and is fed through standard coaxial connectors.
The erection of a MONOPOLE antenna does not require any heavy equipment.
It is done with a few accessories provided on request.
