I've been looking to *up* my ham radio experience by constructing a few
projects. Though I have a few toys already, (Spec analyzer, sweep gen
scope) I've been looking at purchasing an RF analyzer. I am looking for
something that can easily scope out resonant circuits, antennas and
measure impedance and reactance.

The MFJ series seems dominate in the market but does not cover all the
freq ranges I'm interested in. I've found a company called Autek Research
who seems to make a few continuous analyzers but find very little about
them on google.

Are there any other companies making RF analyzers?
