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.

cheers, JB.
