An antenna assembly includes a camera, a plug, and a radome. The radome is configured to house one or more antennas. The radome defines an opening extending between its interior surface and its exterior surface. The camera is positionable at least partially within the opening of the radome. The camera and the radome define a passage between the radome and the camera when the camera is positioned at least partially within the opening of the radome. The plug defines an opening extending between its interior plug surface and its exterior plug surface to receive at least a portion of the camera. The plug is positionable at least partially within the passage to substantially prevent contaminants from passing into the radome via the opening of the radome. Other antenna assemblies and methods relating to antenna assemblies are also disclosed.
