Someone is telling little porkies.... I have an Antenna book written in 1928 that has half-a-dozen variants on that design. Carver may be many things - but reinventors of the wheel - not hardly.

I've heard of people making huge AM loop antennas in their attics... if
you have a better design or one that's easier to make, please do share
before I start on one at some point here!

I will have to dig out the book and scan a few pages for you. Give me a bit.

Search the Internet; there are many sites that describe loop antennas.
Most of them are tuned as opposed to the untuned one described in the
link above. Tuning makes them more responsive to a particular frequency
than an untuned loop. It also requires that the user tune the loop each
time he changes frequency. Some of the loops on the Internet have a
Faraday shield which helps reduce interference from local sources.
Any loop antenna by itself is unlikely to work well with a car radio.
Car radios are optimized to work with the antenna that came with the
car. Some intermediate circuitry will be needed.

adjusted, I wondered what the purpose of that was. It looked like it
had some kind of foil shield/box incorporated into it. Thanks!
From Hugo Gernsback's 1922 opus - "The Future of Radio" - paraphrased for brevity:to ground, the other to the antenna input. Try both ways.
A loop antenna may be from 12" to 120" across diagonally, usually consisting of between 5 and 15 turns of wire. Coupling to the radio may be direct, or indirect. As the loop antenna does away with the ground connection, one end of the loop may connect
A small-value variable capacitor may be placed in series with the antenna connection for tuning purposes.
A loop antenna is highly directional, even a few degrees off the ideal angle may cut off all reception.
A loop antenna may be coupled with another loop antenna (placed close together) to increase the receiving bandwidth. In this case, a small variable capacitor may be placed within the loop for fine tuning.
That took about 4 pages.

There is this - that will allow you to rotate the antenna from a distance. If you have enough 'swing' in your attic for a larger antenna than on top of the console, both the size and the height will give you an advantage. Again, loops are highly
