I will echo Demetre Julian - we're not trying to drive you off - and
I suppose your comment " Due to the intemperate diatribe directed at
me by another member of this list" was directed to me - if so I
apologize if you took it as being intemperate.
But you keep insisting on things being one way when the laws of
physics have time and time and time again proven them to different.
You keep asking for help in trying to solve a problem that appears by
conventional theory, unsolveable. Also in some ways, not in need of a
solution - you might be perceiving a problem that doesn't exist.
A lot of people have offered you a lot of good help and tried to
point you in the direction to where you can help yourself more.
Eventually, people tend to get weary of pointing their finger in the
same direction.
I never studied Physics in school. I had to finish 6 months after the
rest of my class due to a run in with an instructor of a required
course. I never went to college. I could have if hadn't I been lazy
and bored by school. (I used to read books in primary school upside
down because it was more of a challange - helped in later in business
when sitting accross the desk from a customer or sales rep)
But I was curious about things wireless, and I read - a lot -
practically everything I could ever get my hands on about
antennas..... and a good amount of it from antenna companies is BUNK.
When I first started reading Moxon's book, after about 2 chapters, I
had such a headache, you wouldn't beleive!!! I didn't get a lot of it
at first, or at the second reading.... but I kept at it, and
experimented - a lot of them were failures, but others were
fantastic.
I was able to work all states and about 30 or more countries with a
12' dipole made from mobile whips that was 3' off my second story
balcony of a 4 story building of wiremesh and concrete running 50
watts. That was about my 10th attempt for a good working antenna at
that QTH.
So keep at it - maybe you will find the secret - here is a hint:
Moxon talks about radials for a vertical that are shortened with
loading coils working better than full length ones.... haven't had
the time to try it, but that may be the holy grail you seek - try
using your ATX as the "counterpoise" for the MP1 - see what that
does.... I am anxious to find out - and make the lower mast of the
MP1 about 3' - that should yield between 3 - 6 db better signal. And
maybe mount it on a camera tripod so it is higher and the "radial" is
less coupled to the earth - yes - a L-pole - I think it is your best
chance.

Thanks, Demetre.
I did download the W4RNL article but it was a bit much to get my
head
round. It is a very long time since I did school physics and
learnt
about fields and stuff. All I actually wanted to do was find a
way
to
tune the MP-1 so it presented a good SWR and I could use it with
the
817 without a tuner.
Due to the intemperate diatribe directed at me by another member
of
this list I no longer wish to contribute, so I shall unsubscribe
now
and let you carry on discussing computer software and opening up
receive coverage and similar matters in peace. Perhaps in a few
months I will once again be able to go up in the mountains and
use
my
817 as I intended, and perhaps one day, Demetre, I shall have the
pleasure of a QSO with you.
Until then, 73.
Julian, G4ILO
Hi Julian,
No need to be so radical man. I think everyone is trying to help
here, not to send members of the group away. After all these Groups
are for this reason, where we can all tell our opinion and help
each
other. Nobody here is expected to be a rocket scientist and I do
not
anyone of us here is.
On the other hand perhaps you could continue this discussion to a
more specialized group such as the HFpack. If you are not already a
member of it, I think it would be a good idea joining it.
As for a QSO with me Julian I am visiting the UK on 20 July and
will
stay there for 2 weeks. Please e-mail me privately if you like to
sv1uy@y... telling me if you are going to be there.
Also I will be QRV this Sunday at 04.00z on 18,157 KHZ and at
08.00z
on 28,337 KHZ and at 08.15z on 21,437 KHZ on my Sunday trek at Mt.
Ymittos talking to Keith G4MSF and Terry G0EHX. You are welcome to
call me. Feel free to break the QSO.
