A packaging container with a base and a cover hinged together is provided. Base and cover are hinged together by first and second cooperating formations formed integrally with the base and the cover. One of the first and second cooperating formations provide sockets and the other cooperating formations provide pin portions removably receivable in the sockets to be rotatable therein to allow the cover to be rotated relative to the base between an open position and a closed position. Number and locations of the first and second formations are such that one or more are used for hinging, while others provide structural support between the base and the cover when the container is in the closed position.

An antenna assembly suitable for use with a microwave-based level measurement system mounted on a vessel. The antenna assembly comprises a rod antenna having a mounting member with an integral sealing ring. The antenna is molded from a conductive polymer such as PTFE. The sealing ring is also formed from the same polymer as the antenna. The sealing ring may be formed as an integral component of the mounting member molded from a polymer material or as a separate ring element which is welded or otherwise affixed to the mounting member. The antenna assembly is coupled to the level measurement apparatus using a clamping mechanism. As the clamping mechanism is secured to the mounting member, the sealing ring is compressed and deflected and in the compressed state provides a seal between the level measurement apparatus and the section of antenna extending into the vessel. According to another embodiment, the antenna assembly is adapted for and mounted in a horn antenna. The horn antenna is coupled to the level measurement system and extends into the vessel.
