One of the most important design
considerations for any system is the
pointing accuracy and stability of the
antenna to ensure it stays on satellite
whatever happens. Cobham SATCOM
invented the stabilized antenna systems
and continues to lead the market in
terms of robustness, vibration and
shock tolerance. The Sea Tel 2400 is no
exception and has passed rigorous testing
?to include IEC 60945 and MIL 901D class
B testing for shock and vibration as well as
temperature testing to ensure the Sea Tel
2400 will continue to operate and survive
in the harshest environments experienced
at sea. The robust antenna design allows
the antenna to absorb a tremendous level
of shock and vibrations with no impact on
performance or longevity of the system.
Shipped in two crates in three preassembled
units, the system is easily
installed in a single day. As the
installation footprint is identical to that
of Sea Tel 9711, there is no need to
change platforms when upgrading to
the Sea Tel 2400.
The Sea Tel 2400 series allows
customers to purchase a dual band
system now and upgrade to Triband
whenever you decide to do so. There
is no longer a need to tie up capital for
equipment now that you will not use for
a year or two – or may not be certain
that you will ever need it in the future.
With the Sea Tel 2400 you are ready for
the future. What you purchase today will
be ready for the demands of tomorrow.
