ABSTRACT:
An enclosed antenna assembly having a non-rigid, floating connection between an aluminum tray and a radome along the length of the assembly. The non-rigid, floating connection along the length of the antenna assembly provides a seal that is not damaged or degraded as a result of thermal expansion and contraction of the dissimilar materials. The tray and radome are joined along their length by a tongue and groove type connection, which allows free movement along the major axis. A top end cap provides the only rigid connection between the tray and the radome. A bottom end cap is fastened only to the radome. The design of the keyway and the top end cap prevent direct water intrusion. The bottom end cap includes weep holes to allow condensation to escape from the interior of the antenna assembly.
