<p>An assembly of mechanically steerable directional radio antennas, comprising a primary antenna and at least one secondary antenna, arranged such that the or each secondary antenna is capable of being physically steered over a limited azimuthal arc relative to the primary antenna, and is at least partially within the swept volume of the primary antenna. By allowing the swept volumes of the antennas to overlap, a compact assembly can be provided, whilst by limiting the azimuthal movement of the secondary antennas relative to the primary, it can be arranged that the antennas to not foul each other.</p> |
