300–900 MHz Midband Array Design for the Lunar Farside Technosignatures and Transients Telescope

United States National Committee of URSI National Radio Science Meeting
The Lunar Farside Technosignatures and Transients Telescope (LFT3) has been proposed to observe radio signals in the shielded zone on the lunar farside. LFT3 will include several low-gain antennas covering frequencies from 1–1800 MHz.
