Hi Walt, I don't know if you know or not, but the Carolina Windom
is designed for the vertical section to radiate so it has a
radiation pattern which is a combination of a dipole and a vertical.

Indeed, all the interest of the thing..., hence my question.
But I wonder also about the QRM pick-up along this vertical segment...
I will have the answer in two weeks.

I have used 160M Carolina windoms for the past 5 years or so and have
found them to be really good performers. The higher you can get the
vertical element off the ground the better (I have had good results
with it only 20' off the gorund....Radioworks recommends more). I have
never modeled it, nor had experience with G5RV, but compared to a half
wave dipole at similar height, my "impression" is that it performs at
least as well, probably better, plus multiband. Beward you will need
to use a tuner with it, and if you are running legal limit, be careful
of your SWR's as you can burn out the balun or RF choke (they are not
traps). There has been a lot of debate about this antenna, but I can
tell you the 160M version works quite well on all bandsl.

Hi,

160m long 20' high ? That must be interesting and u had to confirm over 100
dx with such a length...
I very well know these problems of SWR etc,and many others. I am an OT you
know,... Hi! I learnt the lesson in the past in experimenting live a bad
SWR... youth errors as one tells... but interesting because I never more
forget the lesson, like many others in experimenting myself.
With some respect it it far better to be chocke a second and get a little
blister due to a SWR over 5:1 using a kW amp that having hours of theory...
because you cannot fix your idea on concrete things.

For the rest, of course the heigth (and length) are VERY important, all
using a dipole or windom all work fine or almost from 8m high and 20m long
and up. Below your radiation pattern is seriously affected compared to the
ideal solution (say 2-lamba over 12m high). And you feel that very well when
trying to call CQ DX and even simple CQ up to 5000 km away.
To get an idea simulate these specs in modeling software like multiprop that
use a VOACAP engine, or even nec, hfant and others.

See my best site for detail.
Thanks for the help.

No, no, no.. I said the vertical element was 20' off the
ground....bottom of the vertical feedline 20' off the ground, means
antennas height in the center was about 40-50'.

Why would QRM be a problem ? The beter the antenna the more signal it will
pick up. Maybe you ment QRN (noise) instead of M (undesired radio signals)
?

No ! I speak of QRM, made made, due to vertical segment (vertical polarized
I believed) that, i thougth, 'd pick up more QRM, in the same way as a
vertical antenna coupled to a dipole tight horizontally e.g..
But in this case it doesn't as this is a common-mode choke balun ; there is
no RF radiation form the coax.
In all cases I will see the result in the field very soon, adn could
appreciate both designs (dipole vs. windom).

It is designed to radiate some vertically polarized energy so it
is also designed to receiver some vertically polarized energy.
That would render the Carolina Windom virtually useless at my QTH.
