Don't get bogged down with aerial types.....not necessary for a domestic radio. Tuned aerials and elaborate arrays were specialist types used for much more serious work...particularly in the Amateur Radio field where accurate matching of receiver and transmitter aerials was essential.

Domestic radio's were different and built with the ordinary user in mind....a piece of wire strung along the picture rail or hanging out the window was about as 'elaborate' as most people got!
