Integrated antenna arrangement
An antenna arrangement includes a directional antenna assembly, the directional antenna assembly comprising a directional antenna intended to be mounted on an interface delimited by a stationary support structure, the directional antenna generally extending according to a main axis perpendicular to the plane defined by the interface, wherein the antenna arrangement further comprises a rotatable base mounted on the interface, the rotatable base comprising a pole integral with the rotatable base, the pole extending in the direction of the main axis, the rotatable base being rotatable about the main axis 11 , a rotation of the rotatable base actuating the rotation of the pole about the main axis.
1. An antenna arrangement comprising:
a directional antenna assembly, comprising a directional antenna mounted upon a stationary support structure through a connection base of the directional antenna, the directional antenna generally extending along a main vertical axis perpendicular to a plane defined by said stationary support structure; and
a rotatable base rotatably mounted about said stationary support structure and a pole assembly, said pole assembly comprising a pole mounted on said rotatable base, said pole extending in the direction of said main axis, the rotatable base being a base different from the connection base of the directional antenna assembly, the rotatable base surrounding the connection base of the directional antenna assembly, said rotatable base being rotatable about the main axis, said rotatable base being configured to control the rotation of the pole assembly in azimuth, about the main axis, a rotation of said rotatable base actuating and controlling the rotation of the pole about the main axis so as to enable relocation of the pole outside the line-of-sight of the directional antenna, the upper end of the pole lying above the upper point of the directional antenna assembly.
