| Andy and all,
|
| Everyone has to make their own decisions as you pointed out.  I recall
that
| Wayne is a backpacker and I would imagine he desires everything on one
| package so he can pick it up and take it on the trail, and for these
goals,
| coax loss is not really a primary consideration (feedlines are short in
| temporary antenna setups).  We who have to contend with loooong coax runs
| will suffer from excessive losses when we place the tuner in the shack -
| unless we use antennas matched to coax at their feedpoint and the
resulting
| separate antennas for each band.
|
| Multiband operation of antennas makes life more difficult, and for my part
| requires that matching the feedline take place at the point where a
| transition is made from coax to either the radiator itself or to low loss
| open wire line.

| | The issue of where a tuner goes does not have a single answer.
| | I debated Wayne on this three years ago in Dayton, and we used
| | Roy Lewellan as a reference.   Wayne wasn't satisfied with Roy's
| | response.
| | So last spring, the subject came up again very briefly on the
| | reflector.  Referencing W7EL, wasn't good
| | enough to get my point across, so I asked LC Cebik.
| | Here's his response.  Until Elecraft provides a good way to remote
| | their tuner, which appears to otherwise outperform my LDG RT-11,
| | the LDG is staying outside driving the vertical element of my antenna.
