I do two things for mine.  First I install a DC blocking capacitor, 0.01 
ceramic disk rated at kV, in series on the 50 ohm signal or coax side. 
 I've never had any problems with the transformer itself.  Then, out at 
the terminating resistor box, I parallel up a bunch so that I have 12 
watts of power capability so the resistors don't fry and then I parallel 
that bunch with a gas discharge tube rated at 350 V.  Phil  KB9CRY
