Australia,
like most developed nations, is saturated with ubiquitous wireless
radio-frequency services, associated with broadcast services, telephony
services, networking services, and miscellaneous other RF
communications. This webpage is intended to display typical examples,
photographed in urban/suburban areas of Australia.

Cellular
/ WiMax Towers

Keysborough, in the South-Eastern
Suburbs of Melbourne. A circular antenna for a terrestrial
point-to-point link is at the base of the set, and may be used for the
base station network tie-in.

Monash
Uni Caulfield Campus
|
Monash University, like many
organisations which own multiple multi-storey buildings, has exploited
available rooftop space for the installation of antenna farms. Most of
these images depict Bldg S at Caulfield. Identifiable services include
cellular telephony, WiFi, and terrestrial microwave point-to-point
links. These images are of sufficient resolution to clearly show
mounting structures, hardware for angular alignment, and where
applicable, the RF cables connecting the antennas to the terminal or
repeater equipment.

Terrestrial
Broadcast Service Antennas
|
One of the multiple television
broadcast towers on Mount Dandenong. The dipole arrays for TV services
are clearly designed for minimal sidelobe emissions above and below the
broadside plane of the array. Note the opportunistic use of the tower
for microwave terrestrial services.
|
Satellite
Broadcast Service Antennas
|
Satellite television broadcast
services are widely used in Australia, and are especially common in
some suburbs. The depicted examples were all photographed within a
circle of 100 metres, in which five households possessed satellite
antennas.
|
Household VHF/UHF Television Antennas
|
Television broadcast services in
Australia largely operate, as in most developed nations, in the VHF and
UHF bands. The most common antenna designs in Australia are variations
on the Yagi theme, either for VHF or UHF bands, or sometimes both.
