Hi Lee,
I remember well the Gotham Verticals. Had one when I was a novice back in
1966.. It was basically made of EMT and had a large Base Loading coil .
knowing nothing of how verticals worked in that day I had it set up in the
side yard of our home with only a 4' ground rod as the other half of the
antenna.. the losses must have been awful.. But in my ignorance I still
managed to work several dx station Crysal control about 15watts out on 40M.
Never could get it to load on 80m though , If I remember right they were
about 18 ft tall. I've since used that same design at other location
(homebrewed ) to good effect. But a top hat loading will help much on 80m
also. and lots of radials.
you can find the basic design on the web at http://www.arrl

73 & Good Luck

Back in the days when men were men and ham radio operators were kids, there
was a company that sold verticles-Gotham. I've alway wondered what the deal
with the Gotham antenna was all about. All I had to go on was old QST's from
the 50's and since I had no money in the 60's I could never afford a
commercial antenna.
I've been pondering building a verticle using parts from the hardware store
that could be used on 80 meters. Like using a loading coil at the base of
the antenna. I am sure that this has been done before, but as I was thinking
about it....the Gotham antenna company came to mind.
Is this what they did with their 80 meter verticle...use some sort of
loading coil?
