I do not know why Philco covered their loop antennas with paper in their 1940 models, but they did, for whatever reason. Thinking as I type...probably to help protect the semi-fine wire (around 24-26 gauge or so) used in the 1940 loops.

The antenna mounted under the top of the cabinet must surely be the SW loop. All of the larger 1940 Philcos had a single turn loop mounted in the top of the cabinet to pick up shortwave.

"Built To Receive Television Sound" - It was planned for Philco's early (prewar) TV sets to broadcast the sound via AM on a low frequency (between 540 and 600 kc) to a nearby AM radio, in the same manner as their "RP" series of wireless phonographs with built-in flea-power AM transmitter.
