[Elecraft] grounding and counterpoise

[Lyle Johnson]

Hello Ron!

If you look at pictures of the old 707 or 720, you'll often see a 
"stinger" pointing forward from the top of the vertical stabilizer. This 
is an HF antenna.

There was often a stinger pointing aft on a wingtip of a 747 (before the 
400 series aircraft).  This, too, was an HF antenna.  The 707-style 
system worked pretty well; the 747-style had a *lot* of static due to 
bleed-off from the aircraft.  The antenna became an extension of the 
airframe static dissipation system.  This was (and is) a poor location...
