[DX] dipole vs horiz. loop for low band DXing

[BILL CARNEY]

Hi John....You might have a look in the ARRL Antenna Book...there used to=
 be
a article called the "Loop Sky Wire" by W=D8MHS. Actually I worked him on=
 that
antenna on 40M CW and he had a very good signal using only a 100W...Its
basically a Horizonal Loop.. a full wavelength long using the 1005/freque=
ncy
formula approx 30 feet up and fed with standard 50 ohm coax... although
according to the article you tie the braid and center conductor together
then used it with a ATU. I also knew a local ZL3 who had one  (now a SK) =
and
had it made for 80M and he did very well with it..DX wise=0D

If you can do it John..give it a go! You never know how good a antenna wi=
ll
do until you try it . Hi=0D

Personally I have played around with loops over the years mainly with Del=
ta
Loops and they do work very well...actually most closed loop antennas are
much quieter on the recieve side which may help you with your static prob=

I am currently running a homebrew version of a G5RV=0D
dipole. It is about 110 feet long, roughly=0D
horizontal, with the one leg dipping down to about 7=0D
feet high. The center is probably 20-25 feet high,=0D
and won't be able to get it any higher anytime soon. =0D
It seems to do OK on low band dxing, but does catch=0D
quite a bit of static. I used to use a random=0D
wire,around 130 feet or so at another QTH and had very=0D
good luck with that on 80 and 40 meter DX. Don't have=0D
the space to put up such a wire today, but could turn=0D
the dipole into a closed horizontal loop. It would be=0D
about 200 feet or so in diameter, at the same=0D
heighth-approximately 25-30 feet off the ground.=0D
=0D
Is this worth it? How would this loop perform=0D
compared to the dipole. I understand that the dipole=0D
has a crummy take off angle due to its low height, but=0D
it is as high as I can currently get it. Use it on 30=0D
to 80 meters, and wonder whether adding the extra wire=0D
for the loop will improve performance, or hurt=0D
performance.=0D
Any advice would be most welcomed.=0D
