[Boatanchors] Receiver Antenna Input Question

[Carl]

They found that out decades before Desert Storm. However a neon has a 
rather long delay before it fires if it isnt biased to a more useful 
voltage. SS front ends would be fried otherwise and I dont thing they 
were using tubes in 1991. For SS there are better choices.
