A hundred years ago this month, the August 1923 issue of Science and Invention included a number of pointers for making the most of vacation time radio. The magazine advised against just storing the radio away and waiting for your return.

For example, a self-contained set with a loop antenna was perfect for the job, as shown in figure 1. If you need an antenna, figure 2 showed one way of putting it up, using a kite. If you didn’t feel like flying a kite, you could possible use the body of your car as the antenna, with a stake driven into the earth to serve as ground, as shown in figure 3. If you’re lucky, there will be a fence, which you can use as in figure 4. The car battery can probably be used, as shown in figure 5.

We’ve talked previously about using trees as antennas, and this idea is shown in figure 6. Figure 7 shows how you can put a wire, insulated by a rubber tube, underwater. And finally, figure 8 shows an idea before its time, namely, the slinky antenna, not unlike the one we showed previously, but prior to the invention of the slinky.
