Description:
The AS-2812/SRC antenna is an omnidirectional vertical
biconical dipole. All major components of the radiating and
support structures are aluminum. The central feed section is
protected and weatherproofed by a laminated fiberglass
cover. The AS-2812/SRC may be used with any UHF transmitting
and/or receiving equipment designed to operate within its
frequency range and RF power handling limitations.
Installation: The antenna assembly is supplied
with a mounting pad for vertical mounting. This pad has four
holes for 5/16 inch bolts on a 3 inch square pattern. The
antenna may be installed on a suitable mounting plate having
matching bolt holes.
Considerations: The location for the
AS-2812/SRC should be selected to provide maximum
omnidirectional coverage within the physical constraints of
the ship's structure. Propagation within the frequency range
of the antenna is generally line-of-sight; therefore,
antennas that are masked by surrounding structures may
produce limited coverage in azimuth and/or elevation. |
