Where's the experimental evidence, Cecil?



Ever heard of Ben Franklin? :-)

Every winter here in New England we run numerous experiments, every time
I walk across the living room and touch a metal door knob.

The US military has an ESD specification of 25 KV @ 5 KOhms from a
healthy capacitor as a simulator.

Electro static discharge on antennas has been around for years. It is real!

Dry Climate and Wind are all that's needed. Now, is the Physics at the
air molecule level [Oxygen, Nitrogen, etc.], ionized Oxygen or Nitrogen
atoms, charged dust particle level [that just begs the issue ... how did
the dust get charged?], Van De Graff level, etc.? Who knows?

But, the antenna ESD is a very REAL effect. You can hypothesize the
cause all day. To solve the problem at the system level, I added an ESD
bleed into my antenna switches.

I'm going to filter this thread to the circular file.


No one said ESD didn't exist. But you hit the nail on the head so far
as wind caused ESD, "Who knows?" I don't, and neither does Cecil,
although he thinks he does.
