For most part must agree with all, and REMEMBER, that these are NOT totally
exact-- for instance- done
same with (YE-GADS!) a 6 meter 7 element yagi, with pretty well known
properties, by M-Squared, both in
YO, and in EZNEC-- and the forward gain is more or less identicle, but the
F/B is something else! However, didn't
taper the elements (first 18 inchs at a given diameter, rest of el length, a
smaller size tubeing-- does this make
EZNEC an error prone program? NO! t'was my fault in NOT takeing the time
to input all those extera connections
into the model ! (tho, would be interesting to see it PROPERLY modeled, and
admittedly, YO handles this much easier
for a yagi- did the same for a DX engineering, (elements ALL same diameter)
and forward gain is about the same
and the f/b is within 5 db (the 7 elM squared is about 15 dB different F/B)
But all in all, best to trust EZNEC-
seems pretty much dead on for most applications. as info-- Jim NN7K And,
PS, is nice to see a CIVIL conversation
here! JF

A very rare, welcomed, combination of events has occurred.

First we have a sensible, concise, well-presented enquiry about
inverted-V's.

And secondly we have a response from Richard (Clark) which combines both
his
advanced (never doubted) technical knowledge and his ability (but long
awaited) to express himself in the logical, unambiguous,
easy-to-understand
English language.

Makes a change from the deliberately confusing, psychologicially mixed-up
stuff we are accustomed to. Keep up the good work.

But may I say I have learned a lot over the years from your own
how-not-to-do-it mode of expressing yourself.

Richard, please forgive me for being so forthright in public. I'm on
Valencia red this evening. I'm sure you will understand.

Incidentally, I think the English and American languages, after a
generation's lapse, are coming back closer together again. You get rid of
Bush and we'll get rid of Blair.
