SBS antennas at Federation Square, Melbourne
The Special Broadcasting Service (SBS) is an Australian public broadcasting radio, online and television network which operates four TV channels and eight radio networks. As to what the three antennas are, at this stage it’s a guess but from left to right, these look like a Gregorian sub-reflector parabolic, a grid-pak and a short collinear array surrounded by a cylindrical radome?
Civil emergency service antennas near Nyon in Switzerland
The structure in the centre of the photograph is a bi-conical monopole broadband HF antenna. This has good ground-wave and sky-wave radiation characteristics. If you look carefully you can see the wires running up from the feed point at the base of the support mast to the circular waist disk and then up to the top of the antenna. Its located at a civil emergency services site near Nyon in Switzerland. There was also one of these at Cape Shank in Victoria.
CMS detector life-size model in CERN microcosm display:
The Compact Muon Solenoid (CMS) is a general-purpose detector at the Large Hadron Collider (LHC). It has a broad physics programme ranging from studying the Standard Model (including the Higgs boson) to searching for extra dimensions and particles that could make up dark matter: https://home.cern/about/experiments/cms
