Nick,
Thanks for the thoughts AND for directing me to Bruce Conti's website.
I know Bruce only through the proceedings on this Reflector, but I
copied his diagram to my antenna subdirectory earlier this year.
It never occurred to me that if I "close the circuit" via a base
conductor, I have converted a EWE to a loop, but that what it
amounts to.
I would prefer to simply call it a EWE and let it go at that. If I
refer to it as a "super loop," then that distorts a mental image
of what is happening here.
I suppose there would be little effective difference between a
conductor laid upon the ground and one that is buried, but come
time to mow the yard (about every 1½ - 2 weeks down here in the
"jungles" (excuse me) rainforests of North Carolina, and yes...
one might very well notice a difference!
How's your "Crudley Bathbrush" model 1527 mod. B working?
73 from 77° 25'35.4" W, 35° 22' 36.7" N
where the deer (but no antelope) play.
