Topband: Polyphaser

[Brad Rehm]

I don't know if the policy is still in place, but I remember that
Polyphaser used to offer free testing of their products if you sent them
back to the factory.  Words about it were buried somewhere in their
catalog, and I used the service many years ago when I was about to put one
of their old coax arrestors back into service.

Testing them yourself can be difficult, because it requires a high-voltage
transient generator with known waveform characteristics.  They're not too
difficult to build, but sending a questionable part back to the factory is
the best option for most of us.
