Hi. Does Radioshack still manufacture Part No. 150-1639 or 15-1639, which
is an FM turnstile antenna? Looks unlikely to me.

Was Radioshacks offering a folded dipole arrangement?

Yes, it was just as shown in the Winegard site. Installed one at a
friends mountain cabin and he went from no FM reception to being able
to receive 3. Might not sound great, but for a cabin nestled in the
hills and 75 miles from the nearest broadcaster that isn't too bad.

That's not a folded dipole actually by the looks of it. It's a hertz
dipole. The element on neither dipole folds into a narrow rectangular
shape.
ie

folded dipole ________X_________

i guess it s 300ohm now instead of 50-75

In the picture it's hard to see so I changed my screen resolution and
it looked like it may be folded. Having installed the RatShack model
I can positively say that was a folded dipole. Being that Winegard
makes the antennas RatShack sells I made a leap of faith that the
picture just didn't show that detail well.

In any case, for under $20 it's a good performing omni.

Since a yagi and turnstile are by definition not the same, no.

http://www.winegard.com/offair/pdf/pr-6010.pdf

My recollection of a turnstile antenna is two folded dipoles at 90 degrees
to each other.

A search of radio shack catalog does not show one nor is it in the manual
lookup section
However there is a Lindsay turnstile at URL:

Easily found by using Google -- the searchers friend

Yes. Although not exactly clear, that is what the Winguard is, although I would
have expected a little better radiation pattern. Note the data sheet gives "2
active elements" and the drawing sort of shows the othagonality. The 90 deg of
twin lead is visible too.

There is a part number (150-1639):

Probably very nice quality, but look at the price! Most consumers won't dream
of spending that much.

Antennacraft makes one too.

I'd say $19.20 is a little more like it for the consumer. I'd spray a few coats
of Krylon Crystal Clear on it before I put it up.

I'm in UK. You cannot buy the turnstile direct from FUNKE. Cost of "R.1100-
FM OMNI" to me is appx. $33.00. Google: R.1100- FM OMNI to see the item.
