WW II antenna

[Fansome]

I'm watching "The Guns of Navarone". I just saw an antenna mounted in the back of a jeep; it looked like two magnetic loops, vertically mounted on the same short mast. They were about three feet in diameter, oriented perpendicular to each other on the same vertical axis.

I'm curious as to what kind of antenna this is, and what it's properties are.

Al, that is known as a "movie prop antenna".  It doesn't do anything but sit there, look good and confuse the radiophiles.

Huh. Kinda sounds like me.

people refer to them as a eggbeater. picture is one for satcomms. also there were ones for use at vlf freqs too.
no details on what i used on hf. keeping that to myself..

Other than the "look good" part you're correct, Al. That self awareness training is really starting pay of for you.

There are still a number of commercial vertical CB base antenna's that use the eggbeater design at the top.

Here's a couple of pics of some vintage WW2 direction finders made by Stewart Warner. The first one is the BC470D and the second one is the BC1003. I wonder if they could be retrofitted with SDR technology?

[Fansome]

Ah, ok. I think I understand. So, in reference to the thread in the "Technical Topics" section, using one of these antennas would result in "mixing products"?

Did your S.O. get that adjustment hammer I sent her, Al? You obviously need a tune up.

Actually, I think this is the antenna:

Our buddy Pat Murphy has one of the BC470D's, Al. He bought it thinking he could use it to locate Radio Bob. Sometimes I think our Pat is one dumb bunny.

I wonder how ol' Bob is doing these days. He and I were pretty good friends back in the day. He knew virtually nothing about computers, so I helped him out with things like virus protection and software installation. He sent me a CD with a number of studio recordings of his shows as thanks. And, then, later, he went insane. As we all do.
