We have a Franklin antenna at WHO, 1040 KHZ, here in Des Moines. I've been
told it is one of the few remaining in the country.

Hi Ed,
The engineer at WTIC responded. That station does not have a Franklin
antenna but has "series fed halfwave" during the day and switches in a
second one at night, phased to change the radiation pattern. He also told
me that their 'sister station', KDKA in Pittsburgh, does use a Franklin
antenna. Some members near Pittsburgh may want to roll by for a peek at
it.

There are several interesting articles if you Google "Franklin Antenna"
they are mechanically BIG and require feeding ingenuity (hams are known
for this feature ...) but are stacked verticals, note- phase the top
element
to avoid cancellation.
If memory serves me right WTIC in Hartford phased two of these puppies,
but it's been a long time ...
73!
