HF radio had long been associated with health services in Australia due to its connection with the Royal Flying Doctor Service. New advances in HF technology are resulting in HF being used throughout the South Pacific and neighbouring islands
Agilent Technologies is hosting an Aerospace and Defence Symposium in Canberra and Adelaide (10 & 12 May) focused on modern measurement techniques for testing advanced military communications and radars.
Only a week after their custom-built mobile weather radar had been finished and newly deployed out at the University of Auckland's Ardmore field site, a tornado whirled through
Kathrein is now selling the UMTS/GSM1800 Trisector Pipe antenna that features full remote electrical tilt and special built service area to incorporate a single unit tower mounted amplifier multipack which provides up to 3x double TMAs for the three antennas within the top radome.
Epcos has added the H series to its SIF family of EMC filters that are now available in seven series (A-E, G, H). This family of two-line devices is designed for 250 VAC and can also be used for DC applications. It can handle currents from 1 to 36 A.
Many of us dedicate our working lives ensuring the health and safety of society, or we support those who put themselves on the line, day in day out, because we value the security they provide to our communities
The CSIRO is using some of the latest radio technologies to ensure that the most is made of the spectrum and that users are given the high-speeds of data transmission that they want
While Australia's railways continue to be riddled by different, often incompatible communications systems, the efficiency and continued development of the network are at risk. Antoine Rouot of Nortel discusses a new digital radiocommunications system.
PacSat Antennas has launched a range of 5.8 GHz solid parabolic dishes. Solid dishes have a number of advantages over parabolic grids - particularly in high traffic: better front-to-back ratio (greater immunity to interference); more uniform and narrower beam-width; more robust than panel-type equivalent.
