Hi MK,

You seem a bit wound up... too much caffeine? ;-)

Still others can't seem to understand that effects
too small to measure usually do not matter in the real world.


Total BS in most cases....I seen the lack of decoupling totally
ruin otherwise decent antennas... I've personally tested and
seen easy 3-4 s unit differences in the same exact antenna , with
and without the decoupling section connected.
Decoupling is critical to high performance on VHF/UHF.
All the best designs include it.

Let's see now. You say my proposition that an effect too small
to measure doesn't matter is "Total BS in most cases." Then
you give an "example" where the effect can not only be measured,
but the measured difference is very large "3-4 s unit(s)."

This strongly suggests that you did not understand the original
premise of "effects too small to measure." So let's try another
example, one far removed from antennas.

Let's say that ONE dust mite of 1,489,362 on your body at a
certain time decides to jump off while you're standing on the
bathroom scale--and that this event does not register on the scale.

I would say this too-small-to-measure event does not matter in
the real world. And even if you found a super laboratory scale
that actually could measure the mite departing, I would STILL
say the event does not matter. Your mileage may vary, of course.

Over in a digital camera forum I frequent, they have coined a
term to describe camera geeks who obsess about tiny differences
in camera system performance that have no practical significance
in real-world picture taking. The term is "measurebator."

Perhaps the term would also be useful in this NG. But we'll
probably have to add a new one of our own for the guys who
think modeling trumps practice. I suggest "modelbator."

Last but not least, if someone posts valid data showing that the
performance of an OSJ J-pole can be measurably, repeatably,
and significantly improved by a decoupling device, I'll be grateful
to him/her! And if the decoupling device is practical and affordable,
I'll want to know where to buy one, or how to build one.

Live long and prosper...

You are
starting to attract imitators.


The J pole has been imitated numerous times....
Or are you talking about arrows?

My reference was to a guy in our area who is making exact
mechanical copies of the Arrow design. I suspect there are
others doing the same.
