Embodiments provide tower-mountable base station antenna enclosure systems to reduce effective wind loads of housed antenna components. The enclosure systems can include wind deflection radomes sized to house antenna components and mountable to tower structures by rotatable couplings. For example, embodiments can have a rotational axis that is substantially transverse to primary wind directions, and the wind deflection structures can be mounted in a manner that permits substantially free rotation around the axis. Such enclosure systems can reduce the wind load of the antenna as deployed on a tower, such that a smaller marginal structural impact can be attributed to deployed antenna components, and the antenna components can be considered as smaller structural loads on the tower.

Various base station cellular enclosures are detailed herein. An airfoil enclosure housing may be present that defines a cavity for housing a base station cellular antenna. The housing may have a leading edge and a vent that permits air from external the airfoil enclosure housing to enter the cavity of the airfoil enclosure housing. The enclosure may further include a rotatable coupling that attaches the airfoil enclosure housing to a support structure. The rotatable coupling can allow the airfoil enclosure housing to rotate based on wind such that the leading edge faces into the wind.

A satellite-communications gateway includes a pedestal, a hub movably coupled to the pedestal and supported by the pedestal, an antenna configured for satellite communications, first electronics positioned inside the hub, and second electronics communicatively coupled to the first electronics and positioned inside the pedestal.
