Description: The AS-4014/U is a 35 foot whip antenna designed for general purpose use with military communications equipment. It is particularly suitable for prolonged installation in shipboard marine environments and can be operated in a vertical, tilted or horizontal position in such locations as the deck edges of an aircraft carrier.

The antenna consists of an aluminum radiating element, a fiberglass base insulator and a base mounting flange. The radiator is fabricated in three sections, square in cross section, which taper from 11 inches at the base to 1 inch at the top. The base insulator consists of four 1/4 inch thick epoxy fiberglass panels attached to the bottom of the radiator and reinforced by angle sections along each corner.

The base mounting flange is used to bolt the antenna to a foundation surface. A flange of either steel or aluminum can be provided to suit the installation requirements.

Containers enclosing measured amounts of CRES shot are attached within the radiating sections and atop the antenna. These effectively damp the natural vibrations of the structure at frequencies encountered aboard Navy vessels.

Antenna AS-4014/U can be used singly for general receiving or transmitting applications. It is also used as a basic component in assembling twinwhip Antenna Group OE-214/U for broadband 4-12 MHz purposes.
