Source summary
Abridged source description: improve a cavity-backed spiral antenna's broadband polarisation performance, addressing weak low-frequency behaviour and high-frequency ellipticity that affects direction finding. The replacement must fit the existing envelope and radome. Detailed military sensing specifications are omitted.
