One advantage of a trap-less center-fed wire fed with ladder-line and a
balanced L network tuner is that if it turns out that a reactance arcs
or melts down, retrofitting a more capable L or C does not require
bringing down the antenna. Another advantage is that such an antenna
is more resistant to icing and wind -- especially if the antenna itself
is made from braided phosphor-bronze wire and the mid point of the
ladder-line is tethered with braided dacron.
