Andrew joins global growth
p. 49 · Read in the full issue
THE merging of the telecommunications, information technology and broadcasting and the emergence of a global village is also apparent in the South Pacific. New tech nologies and services are spreading.
ANDREW is contributing to these aspects and in the communications attenna area, it has available: • an omnidirectional I.SGHz antenna developed for point-to-multipoint concentra tors ; and • a 1.5 Earth Station Antenna suitable for TVRO or VSAT applications for satellite communication; The increased activity in the provision of
additional satellites such as PANAMSAT are an indicator of the growing services that are provided through these means. • a remotely adjustable tilt panel base station antenna is available for cellular com munications. The extremely low wind resis tance and visual impact of this antenna, together with its high performance pattern are features worth mentioning. Additionally, the broad band design covering 820 to 960 MHz allows these antennas to be used for any cellular standard. • Point on Point Microwave applications are provided through a modular 1.8 metre GRIDPAK antenna for frequencies up to 3
Ghz providing low wind resistance and low transportation costs, and a 60cm high per formance antenna utilising a reflector suit able for frequencies up to 38 Ghz. • Equipment for increasing the reliability and survivability of telecommunication installation are represented by the availabil ity of coaxial cable/waveguide pressurisa tion/dehydrator utilising the latest mem brane technology, and a coaxial connector incorporating a tuned stub cavity to provide lightening strike protection to coaxial cable inner conductors without the non-linearities and disposal problems of radioactive gaseous arrestors.
