I bought this radio at a farm sale. My question is where to connect the antenna wires. There are three screws on the far right and a piece of old tv antenna wire plugged into a four hole plug receptical. A prior owner’s writing is on the chassis.
Here is the service info for your set: https://worldradiohistory.com/Archive-Ri...48-PQR.pdf Scroll down to pd 95 on you computer's pg counter there it is. Wouldn't be concerned about trying to make it work with have a look under the chassis to see if it's had any service work done to it in recent years. If you could snap a pic we could see what's cookin under the chassis.
When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
The left terminals are numbered 1, 2, 3, left to right. Terminals 1 & 2 are for the AM loop antenna. Terminal 3 is for an external speaker. The connector to the right is the FM antenna, back in the day a set of TV rabbit ears worked fine. Here's a link to the schematic and much more information: http://www.nostalgiaair.org/resources/637/M0013637.htm
Here is a link to the thread about my own restoration of my 48-482. It is a wonderful, sensitive radio when restored. https://philcoradio.com/phorum/showthrea...ght=48-482
This is my own set up and working. When I moved from Providence, RI to my little farm here in Sneedville, TN, for sixteen months I had to wait to be hooked up to the internet. During that time this radio was my only source of news and information from the outside world, and a lot of entertainment too.

In answer to your question about the FM antenna hookup. The original used the plug you have, but someone changed it. The removed the original antenna, which uses the line cord as an antenna by capacitive coupling, and replaced it with 300 ohm twin lead. It looks like one of those standard FM antennas they used to use with stereo tuners. The original used a 19 inch length of 18 gauge wire soldered into the upper left hand pin of the plug, looking from the back with the plug in the socket. The other end of the wire is soldered to a metal tab about 1 inch by 1 inch, which is then insulated on the outside and wraps around the line cord. You slide it back and forth on the line cord until you hit a "sweet spot" where it receives the best. It looks like this. ( I took this picture when I had put the antenna on the new line cord I installed on the radio.)

Oh boy, something to puzzle over! I know that my electronics teacher from high school would just love to watch me puzzle over this radio. I spent a couple of years (1968-70) in his class and my senior year built a Heathkit five tube superheterodyne radio. I was not his best student and l know it now!
I have always had adequate reception on both the AM and SW bands using just the internal antenna. I suppose, if you want, you can hook an external long wire to the left most terminal, and leave the regular antenna also connected. The picture below clearly shows how the internal antenna as well as the original FM antenna connect to the back of the set.
