[Elecraft] KATxxx Remote Tuner

[CUTTER DAVID]

For those with antennas that are "nearly right," eg provide <1.5:1 in a sweet spot but not the entire band, like a beam or a dipole, a commercial matcher that covers a huge range is not justified.  A simple multi-tapped transformer would satisfy those needs.  A relay-switched unit should be relatively easy to put in an outdoor unit quite inexpensively.  I've seen tuners built into plastic tool boxes, small plastic rubbish bins, food boxes.  Take care to use appropriate drain holes and critter filter.
