Interesting thing happened with the antenna last night.
Had the antenna in the vertical position close to ground ( it is a
truncated co linear dipole) And was prevented from joining the local
group because of multiple QSOs on the same frequency!

Hi Art,

I'v noted a lot of HF advice to your MF question. Most of it of the
quality of looking under the street lamp for lost keys because that is
where the light is.

No doubt you were "prevented." They couldn't hear you! How is it
your heard them? You used the same polarization they were
transmitting in. Now, these are two significant clues to your
problem(s).

Elsewhere you've offered:
Well I have put my dipole in the vertical position also which negates use of
radials but I have not noticed any profound differences as yet after a few
days !
Another clue (really the same as the two above) which reveals the
problem of so quickly embracing the presumed proof of this "negation."
You negated nothing but opportunity. Your claim is identical to those
CFA's "FCC tested" in Georgia that are 20dB down from their reference.
Your vertical dipole misses only the phasing circuit to qualify for
the Nomenclature gain.

I would tend to believe this account. Small vertical antennas next to
the ground with no radials, will be just a tad better than a dummy
load on that band. MK

I do believe that where the feed point is will make all the difference in
the world. A similar feed point up in the air but feeding colinear verticals
even tho they may be truncated will blow that thought away!

I doubt it. I use fairly large antennas on that band and still don't
come close to many of the "big strappers" on that band. I've got a
full size inv L, about 45 ft vertical, and also a 42 ft top loaded
vertical. The top loading consists of four 60 ft wires.
Current up the vertical section is nearly constant on that antenna. I
bet that simple antenna will truncate your short collinear verticals
in any direction, and even it's nothing to really get excited about.
