Go to http://exax.net/index.html and scroll down the page to "center fed
steerable wave antenna". The diagram shows how you can feed a 2-wire
Beverage in the center, or anywhere along its length. The two
transformers
in the middle have center taps that pass signal currents from one side of
the antenna to the other side. Therefore the entire length of the
Beverage
is active at all times.
Except with coax, you would not connect across the center tap point. There
would be a direct connection across the shields, since the center has no
common mode (antenna mode) currents at all.
With a true balanced line, the common mode (antenna mode) connection is
across a center tap.
All good topband ops know how to put up a beverage at night.
