Here are photos of the Philco Antenna Coupler, designed to enable use of an external antenna on many 1941 and 1942 Philco models.

As you would see it plugged into the back of your radio, you can see a screw terminal for an external antenna and a switch on top of the unit. There is also a tab with a hole, allowing the unit to be bolted to the chassis.

Back view of the unit, showing the three-pin connector which matches the three-pin jack on the back of the chassis.

Viewed from the top, you can see the two-position switch is labeled "LOCAL" and "DISTANCE."

Underside view of the coupler. You can see a paper capacitor, a mica capacitor, and an inductor. There is also a resistor in there (not visible).
