Description:
The AS-2810/SRC antenna is an omnidirectional broadband
vertical center-fed dipole. All major components of the
radiating and support structures are aluminum. The central
feed section and radiating elements are enclosed in a
laminated epoxy fiberglass radome. An electrical isolating
section is incorporated in the feed system to provide
balanced feed to the radiating elements and large decoupling
from the feed line. The AS-2810/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 base flange has four
11/32 inch bolt holes equally spaced on a 4 - 5/8 inch bolt
circle for use in mounting the antenna. The antenna may be
installed on a suitable mounting plate having matching bolt
holes. The mounting plate must have a center hole to
accommodate the antenna transmission line.
Considerations: The location for the
AS-2810/SRC should be selected to provide maximum
omnidirectional coverage within the physical constraints of
the ship's structure. UHF propagation in the frequency range
of this antenna is generally line-of-sight; therefore,
antennas that are masked by surrounding structures produce
limited coverage in azimuth and/or elevation. |
