Greetings RHF..
I'm really not surprised that others have thought of the Hula Hoop
antenna long before now! I DO appreciate all the links to the groups.
I got looking at the design and as I remember (as a kid) it seemed to
be larger than 26" or so in diameter. In fact, I do notice that the
good folks at WHAM-O amongst others offer various sizes of the hoop.
Obviously they do, in fact, come in different sizes:

However, this would be a bit extreme!!

Here's a great reference for those in the DIY mood! Now this relates a
bit more to the forum.
Now we're talking (or listening as the case may be)..

Greetings Radioguy..
I think this URL link below is probably what you meant.

I personally believe the twin coil ferrite antenna above is a bit
on the expensive side. However, in the end, it's your choice. I
have used the Select-A-Tenna years ago and indeed it does work
rather well relative to the built-in antenna in most portable AM
radios. Since the Terk is using the same principal of design, I
can't see why it wouldn't work equally as well for the MW band.
If you snoop around a bit on the Web, you could probably find
schematics and plans on how to build your own. The design is
fairly simple. The convenience factors are not having to
construct it yourself and that the molded plastic makes it easy
to keep/store and move over the years.
- I've even wondered if anyone has attempted such a
- design with a Hula Hoop with a couple of holes drilled
- at one end to run many turns of wire within. This
- along with the simple capacitive tuning element should
- provide some rather good results for the MW band.
