Hello Deni:

I have had such problems with rain noise. A ground plane antenna mounted
to the side of the house had severe rain static noise.

After checking the antenna and coax it was found that a new roof was
installed and sheet metal pieces where installed on the roof before the
roof paper and roof was installed. After finding this out, the mast was
moved away and insulated from the side of the house.

This reduced the rain static in the receiver significantly. What I think
was happening was the heavy rain static energy was using the mast as a
ground rod, inducing the noise into the antenna.

I have at times experienced severe rain static, but only two times when
the the rain was a complete heavy down poor of rain, that only lasted a
few minuets. I think its possible that some, but not all weather brings
the rain static and most antenna installations will hear it.

I have recently been plagued by rain static on a new vertical antenna,
this a 42 foot vertical fed at the base through an SG230 auto tuner,
and used on all bands. It seems I need a static bleed of some sort, a
choke or resistor. What is the best component to use in an outdoor
environment?
I thought the auto ATU would in itself provide a static bleed path,
but apparently not.

Any thoughts, how have you solved this?
