That's interesting, I thought Craig had built it himself. The database still
shows it as 32 feet (18 degrees) in height.

I hadn't heard the story about the efficiency problems with WOLF's folded
unipole, but this is ironic considering their signal used to cover better
than expected.

 WOLF, which was on 1500 kc prior to NARBA, originally had a 5/8 wave Lingo
pole.  I have an old ad from a 1940 trade mag, showing a photo of this tower
with the caption "One Engineer Tells Another.... The signal far surpasses
any 100 watt station on 1500 KC I have ever heard..."   (I'll send a scan to
Barry to post in oldradio.com)

However, this may have had more to do with salt concentration in the local
soil and nearby Onondaga Lake than performance of the tower itself.  The
neighborhood near WOLF's transmitter was a major salt processing center in
the late 1800s -- brine was evaporated in sheds, so I would expect a lot of
the crystals fell on the ground.

BTW, Lingo is still in business over in Camden, NJ after all these years,
much of their sales are cell site monopoles.
