With respects to antenna matching, i.e.: 50 to 450 Ohms, which is
better to use, an autotransformer or a transformer with an isolated
primary and secondary? I'm looking for the pro's and con's of each.
==========================================

It all depends on what you want the transformer to do besides perform
an impedance matching function.

Otherwise there's little to choose between them. The autotransformer
will have slightly less loss.

More details please.
