All that's inside a polyphaser is a series capacitor and a gas tube to ground.

Mine are solid state. At least the one I dissected after failure was.

At least for incidental (whatever they're called) strikes, doesn't the gas tube 
just conduct for a few microseconds and go back to life as normal?  And able to 
do this thousands of times?
If Pete had a larger strike, and the element sustained more damage I'd be very 
interested in knowing what happened inside the little box to leave it in a 
shorted or a low resistance mode.

A few years ago I made my own.  A bunch of SO239s on a panel with gas tubes to 
ground (about $2 each) and a series cap, or 2 or 3 on the 160 meter antenna.  
So far so good.
