About this file
This document contains drawings and specifications for replacing an existing 20 Meter Elipticus Antenna with a new 30 Meter Elipticus Antenna. The drawings depict the dimensions and structural requirements for installing three 30 Meter Elipticus Antennas, including antenna height, width, ground clearance, and positioning within the required working volume. Specifications indicate the antennas must maintain a 90 degree angle to the ground plane and follow an elliptical shape within set tolerances. The related federal contract opportunity is solicitation number FA8126-21-R-0003 issued by the Department of the Air Force Materiel Command Air Force Sustainment Center to remove the current 20 Meter antenna and replace it with a 30 Meter Elipticus Antenna through full and open competition utilizing a fixed price contract.
