Since I have a matched pair of Johnson 28uH rollers
and no one seems interested in them ... and I also
have a little clear space on my desk ... I thought
I might just throw together an antenna tuner.

Don't have any big air variables on hand.

I want to be able to tune the following:

1.  An approx. 260 ft multiband doublet fed with
commercial slotted 450 ohm open line (160-10M).

2.  An approx. 120 ft. multiband dipole, 160-10M,
coax fed.

3.  Hustler 5BTV vertical, coax fed.

4.  A variety of end fed, coax fed, and open line
fed homebrew wire-type antennas base and portable.

Simple and solid is a high priority.  I have a
MFJ 259B for tuning so I don't have to include any

While I am building this thing I suppose I should
configure it for full legal, or something close.
I'd like to build it on/in plexi or lexi so the
circuitry is fully visible.



Thanks! & 73, doc kd4e
