This is a Memorandum for AFTC/PZIOA establishing technical requirements for a procurement action.

The Department of the Air Force, Headquarters 96th Test Wing (AFMC) at Eglin Air Force Base, Florida is seeking to purchase nine (9) brand name GPS antenna components. The components must meet specific technical requirements including dual-frequency operation at L1 (1565-1585 MHz) and L2 (1217-1237 MHz), with a 2.0:1 VSWR, right-hand circular polarization, and 50-ohm impedance. Performance specifications include a 3 dBic typical antenna gain at zenith, minimum gain coverage of -1.0 dBic at 0° to 75° elevation and -2.5 dBic at 75° to 80° elevation with -4.5 dBic at 80° to 85° elevation and -7.5 dBic at 90° (horizon), an overall gain of 26.5 dB, and a noise figure of 2.8 dB. Physical and operational specifications include 1-watt power handling capability, +4 to +24 VDC operation, 60 mA current draw, DC grounding for lightning protection, 7-ounce weight, 0.70-inch height, 3.50-inch diameter, white color, and 6061-T6 aluminum construction with thermoset plastic and skydrol-resistant enamel finish. The antenna must feature a TNC connector, operate across a temperature range of -80°F to +203°F, withstand 10 G's vibration, and function at altitudes up to 70,000 feet. The required delivery timeline is two weeks after receipt of order (ARO).
