What an interesting artical. A lot of information on the early days of TV in
the US.
I was however interested in the Cone Dipole antenna they had display in a
couple of the photos. I did a quick search for cone dipole on google but came
back with no results. Would be interested in
I believe that the cone dipole was the predecessor for today's bow-tie design.

Perhaps earlier, but basically the same. Bow-ties are simpler/cheeper
to make because they are simply flat sheet metal instead of round
cones.

There will still be TV channels 2-6 on DTV.
There is a Channel 2 in Harrisburg, PA.
It's not as if Broadcast is going to give up that spectrum.
Besides, it's fun to DX TV stations, and is a good beacon system to
