There is no way it will be that broad banded. A sull half wave dipole
will usually cover about 200 kc of the band between 2 to one points. As
far as external tuners, ldg makes a good one, depends on how much power
you need it to handle. If you don't have an amp, I think around the
$200 or less should get you something that would work.
