[Elecraft] Radials for vertical

[Ray Sills]

HI Doug:

I assume you are talking about a vertical mounted on the ground.  If  
so, you might want to consider extending it a bit to 43 feet.. some  
feel that length works well on bands from 80 through 10 meters.  I'f  
not ever done that, so I don't know.

But I have used base loaded verticals in years past.  Some have said  
for a ground mounted vertical, you need at least 16 radials.  If you  
can make them as long as the vertical, that'd good, but even half that  
size is good.  More radials is better.  And length is not critical..  
so you can just use whatever sizes you have.

If you "elevate" the radials... then length is critical, and you would  
want four radials every 90º for each band of interest.

Glad to hear you want to put that AL wire to good use.  :)
