Ron is so right. At the risk of re-re-repeating myself, whether or not an
antenna is resonant, or matches coax, has nothing to do with its
effectiveness as a radiator or receiver of signals. You don't have to feed
it with coax. If you can put up an antenna with multiple radiators or traps
or matching sections, you can put up a single antenna with no traps and no
matching sections, feed it with ladder line or window line (or even twin
lead), and get equal (or usually better) results. I guess guys like coax-fed
antennas because they see that SO239 on the back of the rig,  but it doesn't
have to go any farther than a balun at the shack exit. Enough RF is wasted
every day in long lossy runs of coax to power a year's worth of DXpeditions.
