i'm interested in building an swr meter to use on amateur hf
frequencies.  a chapter of the 1962 edition of the Radio Amateur's
Handbook features an antenna tuner which includes a foward/reflected
power meter, which is driven off something called a ``monimatch.''
since they give instructions on how to construct this device (it
looks like a four inch length of small copper tube, flanked by two
wires, with two strips of copper outside the wires.  the rf signal
passes through the copper tube), is it reasonable to assume these
weren't available commercially?

the meter itself is driven from a diodes attached to either of the
two wires, depending on whether you want to read forward or reflected
power.

are there better ways of making an swr meter 26 years later?  is
there a place to buy items like the ``monimatch?''
