The 38-7 never had a loop antenna.
The RED and BLK terminals were designed for use with the Philco High Efficiency Aerial, a special dipole supplied with 1937 and 1938 model Philcos. It used a two-wire transmission line from antenna to radio. One of the two wires - the red wire - connected to the RED terminal; the other (black) connected to the BLK terminal.
In lieu of the Philco aerial, you may use a longwire antenna connected to the RED terminal; in which case there should be a jumper between the BLK and GND terminals.
