Description:
The AS-2808/SRC antenna is an omnidirectional broadband
vertical center-fed dipole. All major components of the
radiating and support structures are aluminum. The antenna
feed sections are protected and weatherproofed by laminated
fiberglass housings. The antenna may be used with any VHF
transmitting and/or receiving equipment designed to operate
within its frequency range and RF power handling
limitations.
Installation: The antenna assembly mounting
flange has eight bolt holes for 1/2 inch bolts on a 7 - 1/4
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-2808/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 the antenna is generally line-af-sight; therefore,
coverage in azimuth and/or elevation may be limited if the
antenna is masked. |
