I always figured that with the light bulb thing, most of the radiation would be from the coax. But maybe not.
There was an article in QST years ago (July 2000) called "Everything Works" where a guy made QSOs using a light bulb for a load. It was a much better period for propagation though. I found it on line here:
At OzarkCon this year I used a 50 ohm resistor inserted into a small loop of wire for the in-hotel QSO party. I was amazed to work a station in an adjacent state on that arrangement.

Try to use a bulb that will be near 50 ohms resistance under load.

If one uses a 100w bulb instead of a 6w bulb will the resulting signal be significantly stronger? 😉🙈

Sounds good to me. I have used a 6 watt exit light bulb and socket as a dummy load and it worked fine. I used it once with a home brewed tuner and tuned for full brilliance hi hi de Paul
For many years OzarkCon has been the host of the famous Dummy Load Antenna QSOs. An example is at Terry's WA0ITP website.....
Now we have another challenge.....The Lightbulb QSO Party.......
Have not tried the lightbulb in a long time but they do work, and be careful because you may see the SWR gradually jumping High! Old school filament lightbulbs are used!
