Bilge. All of it. A 66 foot dipole is roughly a *half wave* dipole
on 40M and a 134 foot dipole is roughly a *half wave* dipole on
80M. A 33 foot long center-fed dipole is a quarter wavelength long
on 40M but it is not resonant on 40M and ya better not get stupid
and feed it with coax then just plug it into the back of yer radio
if ya wanna work anybody with it.



A search on google on quarter wave dipole will give plenty of
sources.



That's where we started on this sorry thread. Go back and read the
posts, including my 1/4 vs 1/2 wave dipole design done in EZNEC, and
then let us know how well a 1/4 wave dipole works.

Then why don't you build a 1/4 wave dipole for whatever band gets you
into Central PA. We'll do a sked, and see how well your antenna works.

Geeesh what a knuckle headed bunch. I never claimed that a 1/4 dipole would
work as well as a 1/2 wave. However hook it to some ladder line and a tuner
and you might be supprised. This all started when the so called "experts"
here said there is no such thing. All I am saying is go to google and do a
search and it will be obvious to the most casual observer that there is. Was
I too fast for you are do I need to slow down?

Good Idea, I suggest all No-Coders use this as there Antenna of choice

Did you pay Roy for your copy of EZNEC or are you one of the software
bootleggers who steal from Roy Lewallen's work?

Do you know how to operate EZNEC properly?

Why don't you write a Famous Paper on "Why a 1/4-Wave Dipole Will NOT
Work" and have it published in RF Design magazine? [that's an electronics
trade publication, usually well-respected among RF industry folks]

I'd love to see the Letters to the Editor section on that one.

Why bother ? I just used my 20 meter dipole, coax fed with 50 ohm cable on
7.030. The SWR was off the scale.

I then hit the tune button on my FT-1000mp and that piece of junk wouldn't
tune it. So I called CQ for a couple of hours. No replies.

I then called my buddy across town to fire up and give me a listen. I was
S1 and almost in the noise.

So, for an experiment, knowing it was just a lark because the Texas Twit
said so, I hooked up my 40 meter half wave, center fed with 50 ohm coax.
My signal was now 30 db over S9.

Can you get the Texas Twit to explain this for me please.

Just for kicks, I borrowed a tuner from a friend over the weekend. This is a
homebrew job. Hooked it to the 40 meter dipole and loaded the KWM-2 into it
on 80 meters. Made 5 contacts, 3 out of state, all good copy on both ends.
Guess you just don't know how to do it dannyboy.

Yeah your right 'JJ'. I just don't know how to do it. But then I give a
damn if I get a good report.

Works darned great, doesn't it?! Did all my MARS on it, including net
control for nearly a year. So, yer right, apparently the "high" (high all
right) class hams just don't know how to do it!
