[Boatanchors] Johnson Matchbox 275W

[Rob Atkinson]

I have two center fed dipoles I use mine with, one 1/2 w. on 80; the other
1/2 w. on 20.  I can use the 80 m. one on 80 and 40 (and higher up for all I
know) and I can use the 20 m. one on 30, 20, 17, and 10.  Have not tried it
on 12.  But my point is to agree with Bill--the Matchbox is not just a 5
band tuner regardless of what some complain about on the review web sites.
You may have to work with feedline length and try different band switch
positions and experiment with a SWR analyzer but once you home in on a good
setup, you make note of it and returning to it is a snap.
