I wonder, for those of us not having that antenna setup that one could build a tunable loop antenna and between the clamshell lights install the tuning condenser for the antenna with the condenser shaft coming up between the clamshell lights and a small knob atop the table for adjustment. By the same token one could get a small cabinet instead of the table and put the tunable loop inside the cabinet upright so that the antenna can also be rotated as well as tuned and then hidden behind the cabinet door or doors. Thanks for the idea.
Since then I've come up with an even better solution. They had what was called "light socket aerials" back as far as the mid '20s that used capacitive coupling to the house AC wiring for the antenna. I found 3 or 4 different styles and took them all apart to learn how they work. Some used disc caps, some used mylars, but what I stumbled on ended up being an amazing design! It uses a 2" diameter coil to create the coupling. Works astoundingly well on AM and FM, and with crystal sets you don't even need a ground! Man, I wish I could post a picture here of it.....I made one for an electronics genius I know in PA that lives in a poor reception area. With a standard antenna, he was able to pull in 2 FM stations. With mine, he was able to pull in 37, all with the stereo light lit.
You really don't want to put the antenna capacitor inside the box since it will interact and detune the radio circuits. Mount the capacitor on the loop antenna bare or inside a small box/enclosure.
Tim: A connection to earth ground is not required for reception. This is old radio theory. One can use a random length of wire of the same type used for the "antenna" and layed around the baseboard of the room. Alternatively 'balanced" antenna types can be used which connect to the radio Ground and Antenna connections. Dipoles, ferrite loopsticks with wire windings, FM type "T" antennas will all work fine. bill
Real neat. Wish I had me a 20s radio to play around with like that. Sad that the modern electronics required to power it up kind of take away from the antique design, at least in the back of my mind if I were to do the same, but of course no one has B batteries anymore or the likes so you have to do with what you have :D Real clean mounting it under the cabinet.
Ken: You can make up your own B+ battery pack by connecting multiple 9V batteries. Current draw is typically fairly low and a set can last months, depending on usage. Maximum voltage is typically not required so fewer batteries can be used to save money. Sensitivity will generally be decreased. Adjust voltage for your needs.
i still use batteries, i am currently working on putting antenna jacks inside the house to plug the radio into, just trying to find them has been difficult

@@timpoliniak7361 is this all it used? just a RF coil?
@@gtb81. check out my video about capacitance coupled antennas
Kinda ironic that the station is talking about listening to podcasts, when your using a radio that's from the 1920's 🤣🤣😆
