Re post no. 39,

Certainly Post-war 'Telerection' aerials (3 and 4 element designs) used first a 'T' match then with later models a Delta match. They had a reflector-plain dipole spacing of about 0.25 wavelength with a dipole-director (and director-director) spacing of about 0.1 wavelength. They were also inclined upwards at about 15 degrees. I don't know if 'Telerection' was in business before the war. It was a company based in Cheltenham - so somewhat in the deep fringe of Ally-Pally!
