sure it is, i have one for 80m, and one for 40m that were off the shelf

Look guys all of this is very silly, seems like the interest is more
fore arguments sake
than the search for the real truth. I beg you to use Google to read up
on a conservative field,
it probably will be insinia or something like that.
It clearly states that curl is part and parcel of what constitutes a
concervative field.
Now in this case they point out that curl is zero but at the same time
they point out it cannot be left out and state why. So you all that
are so clever can scan the bottom where an indication on further
information is given on curl. Following up on that tip who find an
expresion that includes time i.e. dt. But you are comfortable with
expedias discussion on conservative fields
and as Roy would say as an out, I don't understand! So we look at the
mathematics and decide for a conservative field there are only two
cartesian dimensions used in the equation and we all are aware that
it is paramount when dealing with equations equilibrium must be
maintained at all times and you cannot destable an "equal " sign".
Since curl was stated in dt terms when we looked it up to maintain
equilibrium on both sides of the equation which extends Gaussian law
with " the adition of a moment in time". All very simple, all laws
are followed and equilibrium is maintained. All we have done is used
all cartesian vectors instead of just two which allows us to broarden
the equation to include a time variant field. Gentlemen this is what
it is all about! I know many are not interested and look at it as an
opportunity to spout off. Some with a bit of education say whoa
you can't do that, but for why? Some people want me to write out
mathematical formula which my keyboard is not capable of but why not
argue with expedia instead of me. Now it is being said by some that it
is acknoweledged that the yagi can be beaten! Does your NEC program
confirm that with a sample or does it always print off a yagi. If you
have got a program that can test that out then do it for your own
good. If you haven't then point out the mathematical errors stated if
not for your own good and satisfaction. I know it is difficult to get
a horse to drink but eventually one comes along unaware of the
situation tries things for himself and then looks up and ask what
everybody is waiting for! I have given two areas that you can research
in moments
so that you can debate my errors.For goodneas sake put aside all
pettines and one upman ship and show all that you really are men.If
you are a mathematician then debate around that point. If you are just
a hobbyist but have a computor program then follow that route to cut
me down, but do something that is worthwhile. How many have an answer
to the computor test I gave, probably nobody because their findings
were embareasing. Who with a knoweledge of physics is willing to put
his stake in the ground and debate from that side, probably none. Quit
babling about "I want"
and think more in line with "I can"
