The Payload for Ultrahigh Energy Observations (“PUEO”) is a NASA-sponsored long-duration high-altitude balloon payload. The primary instrument on the PUEO payload is the main interferometer, which consists of 108 dual-polarization quad-ridged horn antennas with a passband of 300-1200 Mhz. This RFP solicits proposals to design, prototype, and produce 120 of these antennas (108+ 12 spares).
