I don't know of any recommended testing procedure, but a diagram of
how I believe the basic (non-DC passing) Polyphaser units are designed
is available from <http://www.iceradioproducts.com/33.htm>. You may
wish to ignore the marketing aspect (I.C.E. make and sell a competing
product, I'll leave the evaluation of the two to someone more
qualified than myself), but understand that there are two main
components, a capacitor in series between the input and output, and a
gas discharge tube.

A short between either in/out and ground is obviously bad, but
otherwise I guess all you can test that high voltage capacitor (non-DC
units should not pass DC). I don't know if it is possible to test the
gas discharge tube itself.
