A multiband antenna feed, an antenna incorporating the multiband antenna feed and a method are disclosed. An apparatus, comprises: a first port which may be configured to convey a first signal at a first frequency. A second port may configured to convey a second signal at a second frequency. The second frequency may be higher than the first frequency. A third port may be configured to convey the first signal and the second signal with a feed for a multiband antenna. The third port may have an inner waveguide and a coaxial waveguide. A first network may couple the first port with the coaxial waveguide and may be configured to propagate the first signal between the first port and the coaxial waveguide.

A pressurization dehydrator comprising an air compressor and a controller connected to enable automatic operation of the dehydrator. The dehydrator is implemented as a freestanding, bench-top unit having a housing that encloses a baffle plate on which the compressor is mounted. The bottom panel of the housing is affixed to the plate using dampers inserted therebetween. The plate has legs protruding through the corresponding openings in the bottom panel for supporting the whole unit in the upright position on the bench top. Some or all of the legs may not have contact with edges of the openings. In operation, the legs provide an efficient mechanical pathway for transferring some vibrational energy of the plate to the bench top, thereby diverting said energy away from the housing. The circuit board of the controller is affixed to the housing, which beneficially reduces vibration levels transferred to the electronic components of the controller.

An apparatus comprising: a first waveguide port configured to support first signals having a first polarisation state; a second waveguide port configured to support second signals having a second polarisation state orthogonal to the first polarisation state; a third waveguide port configured to support combined signals comprising a first signal component having the first polarisation state and a second signal component having the second polarisation state; a waveguide structure, disposed between the first waveguide port, the second waveguide port and the third waveguide port, configured to: split a combined signal received via the third waveguide port into first and second signal components and to provide the first signal component to the first waveguide port and the second signal component to the second waveguide port, and/or combine a first signal received via the first waveguide port and a second signal received via the second waveguide port into a combined signal and to provide the combined signal to the third waveguide port; wherein an end portion of the first waveguide port, adjacent the waveguide structure, comprises, at a first side, a first curved portion having a first radius of curvature, r 1 , and, at a second side, a second curved portion having a second, different radius of curvature, r 2.
