Deni, I would be tempted to wind my own RF Choke. Use a large ferrite core (FT240-61 for instance) and wind as many turns of 20 guage wire on it as you can. Connect it from the vertical to ground and see if it works. Unless you have some unusual condition where the static noise is creating

Deni, My suggestion is that you use a resistor and not a choke. A choke at some frequencies will become a series resonant L-C 'tuned' circuit, and it is quite possible that the choke will resonate in or close to one of the bands that you use. If that is the case you will loose transmitter

Very interesting Geoff, thanks for the comments. I've deliberately not installed those front end diodes in my K2. As to the rain static, we've had very severe rainstorms in France as I believe you too have experienced in the UK and this problem with rain static I have never heard so bad,
