My older Brother who was an electrical engineer, had a Zenith Transoceanic. I don’t remember the model but it only had a few tubes and also had an antenna which could be placed on a bus window with I guess suction cups.

I remember him playing it for me and being amazed that a radio with only something like 5 or 6 tubes could pick up so well.
