PR-422
AM-SW-FM/DAB+ TV Marine Antenna
For Ships at Sea
The PR-422 is an Active Extra
High Performance
Omni-directional wide-band Terrestiral AM-SW-FM/DAB+ TV Antenna (
0.1-30 and
40-860 MHz ) for Maritime use where second rate efficiency is
unacceptable.
The PR-422 is designed for High End Commercial and Military
vessels and is based on a configuration
of 3 circular dipoles (one is a special flexable printed circuit)
coupled to 3
parallel amplifiers (7 transistors) via a separate broadband filter
network.
Maximum performance is assured through use of a newly designed set of
elements and the extensive use of a Network Analyzer in the initial
design and in the
final construction and tuning of each unit. Microwave transistors
provide
needed gain with a minimum of internally generated noise.
Careful engineering and the use of very high quality
temperature compensating components yields excellent intermod
performance and
sharp hand tuned filters greatly reduce the chance of interferrence
from
outside of the TV bands.
This compact and robust antenna incorporates a shell
made of thick UV-ABS plastic which is
injected with polyurethane foam to protect the elements and EMI
sheilded
internal amplifier. The mounting base is cast from Almag Marine
Aluminum Alloy
which is Shot Peened for extra strength. Mounting hardware is made of
stainless
acid-proof steel. The Shielded Low Noise Amplifier is protected from
static
charges and is removable for field repair or replacement.
The PR-422 is at the head of a new 4000 Series Marine
Cassette Amplifier System with ground isolated distribution passives
introduced
in 1998. The Series 4000 is the result of painstaking engineering and
the use
of state of the art components including high performance GaAs
Hetrerojunction
Bipolar Transistors and MMIC devices.
PR-420 is
identical to PR-422 but without AM-SW radio
reception
