<p>A microwave radio antenna assembly comprises a radio frequency head (20) which is detachably mounted to an antenna casing (10) and can be attached or detached by an operator using a single hand. The casing (10) is formed with arcuate slots (14), and the radio frequency head (20) comprises studs (26) which engage with the slots (14). The end of each slot (14) is enlarged so that the enlarged heads of the studs (26) can be inserted through the slots when the head (20) is in a particular orientation relative to the casing (10): the head (20) can then be turned to align with the casing (10), the studs (26) sliding along the slots (14). To remove the head (20) from the casing (10), the head (20) is turned such that the studs (26) are aligned with the enlarged ends of the slots (14) such that the head (20) may be removed.</p> |
