A Philco 40-180 should have a loop antenna inside the bottom of the cabinet, is is missing this may explain the reception issues as the loop antenna is part of the antenna circuit in the front end of the radio, rather then a broadcast band antenna coil mounted on the chassis. A ground should not be necessary for reception on an early 40s radio of any type, aside from a cheap TRF set if there were any still being made at the time.
