The New Extra Performance PR-414
Marine Radio TV Antenna
from Naval Electronics,
Tampa
PR-414 is an omni-directional, active, wideband Terrestrial AM-FM-TV
receiving antenna (0.1-890 MHz) for marine use, specially designed for
craft equipped with one or two Radio and TV sets as on Coasters in
limited
international trade, Fishing-boats, Tugs, Pilot Service Craft and
Rescue
Cruisers, where extra performance in a robust package is appreciated.
PR-414 is a low profile product, based on 3 independent low noise
amplifiers
integrated directly to the omni-directional multi-element antenna. The
antenna's exterior is made of UV protected thick ABS plastic, which
requires
no maintenance. All inner parts are embedded in solid polyurethane foam
for protection from heavy vibration, moisture and sub zero
temperatures.
Mounting hardware is made of Marine Grade Almag Aluminum alloy. The
integral
low noise 3 band 6 transistor amplifier increases the sensitivity of
the
system as well as compensating for cable-losses in the antenna
downlead.
Separating the amplifiers benifits
intermod rejection and allows for more gain with less noise.The PR-414
features high performance 5 Ghz bi- polar microwave transistors, which
are protected against static charge.
PR-414 utilizes a "3 off-set broadband dipole element configuration"
with each element covering a 120 degree view of the surroundings and a
much improved omni-directional antenna pattern when compared with other
antennas.
PR-414 is delivered with 25 metres (80 ft) of 75 ohm RG-6U low loss
coaxial cable and a powerbox with two receiver outputs. Supply voltage
(220/117V AC) 12, and 24-40V DC.
