Since you are talking about 50 Ohms I assume you are talking about a
transmission line. If that is the case you should definitely match the feedline
to antenna at the antenna feed point. Any attempt to match the feedline with a
tuner in the shack only turns the whole feedline into part of the antenna
system. By doing that you have lost any good work in building the antenna.


The feedline is -always- part of the antenna system. If it troubles
you to think about matching in the shack, just think of the
transmission line as part of a matching network located at the
feedpoint. In other words, the feedpoint network is comprised of 50'
of coax and coupla LCs in a box. This network then connects to the
transmitter through a non-resonant (flat) coax line.
