I am using a number of Polyphaser units in line just before my cables enter my 
home. I have opened them in the past to discover that there is nothing more 
than a surge device from the center pin of the antenna side connector to 
ground, then a capacitor from the antenna side center pin to the radio side 
center pin. Matter of fact, I converted some UHF range units to HF range by 
simply replacing the capacitor with the same value used in a factory built HF 
range unit (I forget the exact value  at the moment but it was either a 0.1 or 
0.01uF disc).

This does not provide any kind of static dissipation. Can I simply open them up 
and add a 1Mohm resistor in parallel to the surge device (antenna center pin to 
ground) to allow for static dissipation?

Or will this affect the original performance of the unit?

If this is ok, will a 1/4w or 1/2w resistor handle 2kw key down? I don't think 
anything larger will fit inside. So far the stock Polyphaser units have passed 
the key down test.

Thanks
