DA-240 Antenna
An advanced all composite 2.4m driveaway antenna for easy
installation on any vehicle
The DA-240 is an all carbon fibre driveaway satellite antenna
with a monocoque construction, making it stronger and
lighter than any comparable product. With no heavy metal
structure to support the reflector and feed arm the antenna
has an all up weight of only 240kgs and the tri-fold reflector
design means it can be installed, even on
relatively compact vehicle such as a Mercedes Sprinter,
without having to make structural changes.
The light weight also keeps the host vehicle centre of gravity
low, minimising affect on the
original driving characteristics, a feature particularly
important when considering the design of fast SNG vehicles and
military communications vehicles.
The unique GigaSat quick release system allows change of
frequency band in seconds without the use of tools. Feed
cartridges are available for C-band, X-band, Ku-band,
DBS- band and Ka-band .
When stowed the DA-240 becomes a fully enclosed pod on the
roof of the vehicle with an exceptionally low drag
co-efficient, again
designed not to affect the driving characteristics of the host
vehicle.
When deployed, the pod turns about its own axis during azimuth
adjustment keeping overall dimensions to a minimum.
This is vitally important when considering installation of
other roof mounted ancillaries such as generator radiators,
air conditioning systems and pneumatic masts.
Inside the pod there is space for a pair of 750W HPA’s with
block upconverters, redundancy system and/or phase combiner.
Mounting this hardware in the pod provides the obvious
advantage of more space inside the vehicle but additionally
also provides the less obvious advantages of
additionally removes noise and heat from inside
and reduces losses between the HPA and antenna.
