Thank you very much for the results on 8 radials.

As expected, it seems that for small numbers of radials the resonance
effects are begining to appear again.

I have ideas as to why this should happen.



Hi Reggie,

You "should" if you had read Brown, Lewis, and Epstein. They
discussed this nearly 70 years ago.


Cut 'im a break Richard! He was just a little kid at the time! ;^)

Default Radiating Efficiency


They've shown that with about 100 radials of 0.4 lamba length the

result is
almost perfect ground, regardless of the ground conditions beneath

the radials.

I contend that using the radial setup as described above will always

result in a
near-perfect ground at any HF frequency, with close to 100 percent

efficiency.

Would you not agree?

======================================

My dear Walt,

I haver never disagreed.

How can one disagree with a statement of the bleeding obvious?

Indeed, my program RADIAL3 confirms it.

And so will NEC4 if you will allow it time to generate some results.
