Description: The AS-2805/SRC is an omnidirectional trussed monopole antenna. The antenna consistsof a box type aluminum mast with four wire rope trusses from the mast to outriggers at the base of the antenna. The wire trusses are insulated from the outriggers by fiberglass rods. The fiber glass base insulator is an integral part of the mast section. The AS-2805/ SRC may be used withany transmitting and/or receiving equipment capable of operating within its frequency range and RF power handling limitations. It may be operated in a vertical, tilted or horizontal position as in an aircraft deck edge installation.

Installation: The antenna may be installed on the ship's deck or structure by means of an adapter piece fitted below the spreaders. This piece is fitted with angles drilled for 5/16 inch mounting bolts. The truss wires must be stressed to specifications after initial installation.

Considerations: This antenna may be installed on a base tilting mount where required for aircraft operations. The antenna may be mounted directly to the tilting mount using the regular antenna base.
