Default Quarterwave vertical with radials

Who said anything about two radials?


Actually YOU did. Several times as a matter of fact.

I am reporting
the standard model with four radials. I was away
from my computer for four days over the holidays
and may have missed the two radial discussion, if
there was one.

The radial radiation cancellation that I earlier
described was based on four radials, certainly
not on two.

Here is what you said on this very thread:

It's pretty easy to understand. Any two radials,
180 degrees apart and high enough, should theoretically
cancel each other's radiation in the far field.

Maybe reading one of your own posts will jog your memory a bit. In it
we see you VERY CLEARLY stated two radials would cancel each other's
radiation.
