 Developed by a second team at Bawdsey Manor led by "Taffy" Bowen, the new radar had to operate at much shorter wavelengths in order to limit the antenna sizes to something that could be practically fit on an aeroplane.After considerable experimentation, the team settled on a set working at 1.5 meter wavelength, about 193 MHz in the VHF band.In early experiments with the new set, the team found that detection of other aircraft was problematic due to their target's relatively small size, but especially reflections off the ground.
