The earth's electrostatic field is about 100-300 V/m (vertical) on a clear day but you need an electrometer to measure as there is virtually no current.
Something to think about with antennas - and lightning.

I was relaxing quietly one day some time back in the lounge and noticed a semi regular quiet ticking sound in the background (maybe once every 20 seconds or so), took a short while to locate the source but found it to be the coax plug on the end of the disconnected antenna, their was a nice little (but weak) flash of static electricity jumping between the plugs center pin and it's outer metal part, the weather was average for our part of the planet as far as I can remember (no lightning around at the time).
I now prefer to keep all unplugged aerials with a short to ground on them.
This is in the UK - not exactly known for a particularly dry atmosphere, certainly not this year anyway!
