Philco 620 Antenna
#2

Hi Dave

There are two Fahnestock clips on top of the chassis. Look carefully at these - you will see ANT stamped on the chassis next to one of them, GND stamped next to the other.

The clip with ANT stamped next to it is for a simple longwire antenna. 20 feet of wire connected to this clip and run along the baseboard of the room the radio is in will bring in stations. A longer wire run outdoors, as high as possible and away from trees and power lines, will make the radio perform much better.

The two screws on the back of the chassis, labelled RED and BLK, are for the Philco High Efficiency Aerial, a half-wave dipole sold by Philco during the mid to late 1930s and designed to be connected at the set's RED and BLK terminals. When the High Efficiency Aerial was used, nothing was connected to the ANT clip.

Finally, the clip with GND stamped next to it is for chassis ground. You can usually get away with not connecting this to anything if you live in an area with good AM signal strength. Connecting the GND clip through a wire to a cold (METAL) water pipe* or copper ground rod driven into the ground outside the home may improve performance.

* If a cold water pipe is used, it must be metal! PVC pipe is plastic and, therefore, is useless as a ground since plastic is an insulating material. If your cold water pipe is metal, a simple radiator hose clamp may be used to clamp the stripped, exposed copper of your ground wire to the metal pipe. DO NOT DO ANYTHING to the pipe that may damage it or cause it to leak! And BE SURE that is the cold water pipe you are messing with, and NOT the gas line!
