Hi again -

I no longer aspire to cornering you into an unbiased comparison.
I can see you're much too crafty for that! ;-)

But I don't want you to think I'm easily fooled, either.
So a couple more comments below...

But trees absorb energy from the monopole which has no gain
to waste. Trees absorb virtually no energy from a dipole.

OK, we need to assume that you have a couple of trees that
are 130+ feet apart, because you say you are using them to
support a dipole of that length.

So instead of a "T" between the trees where the top is a
dipole and the vertical element is the feedline, why not
a "T" between the trees where the top is a support rope
and the vertical element is a monopole? Do you think
a couple of trees 65+ feet away from said monopole
would suck up all its radiated energy? And if so, why
wouldn't they clobber the much closer, high-impedance
ends of the dipole?

BTW, I repeat that I'm NOT trying to convert you to a
different antenna type; I'm merely advocating some
technical objectivity when making comparisons.

3. As to the gain figure, you seem to assume that the
dipole is always operating at the peak of one of its
lobes, and never has to operate in one of its nulls.


I never operate my antenna in a null.


This is quite a remarkable feat! Do you only talk to a list
of favored stations that are known to lie in your lobes?
Or do you refuse to answer a list of stations that lie in your
nulls? (Or if they're DEEP in a null, you might be unaware
of their existence, I suppose.)

I also don't drive my
pickup one mile per hour even if I only average driving it
one hour per day. Seems by your logic, I should always walk
since I can walk faster than the average speed of my pickup
over any 24 hour period. :-)


I'm afraid this analogy is so strained and inapplicable that
it doesn't really need a response.
