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.
