THE "SLICK SIX" 6 METER HORIZONTAL
DIPOLE by Larry Gordon, KK5ID
I built this 6 meter horizontal dipole so I
wouldn't have strings dangling from the end of an inverted V. (And also
to have horizontal polarization on 6 meters.) This antenna works the best
of all I have ever made, easy to adjust and can take the weather elements
that Texas can hand out.
It's small, only about 9 feet 4 inches
from end to end, (see drawing below article) so it can be configured for
other bands as well. I used the standard formula for a dipole (468 / Freq
mhz = total feet. The lengths in the drawing below are for
50.1mhz.
The 6 meter dipole can be designed for any portion of the
6 meter band you desire using the formula. Feed it with 50 ohm coaxial
cable as usual.
The "Slick Six" 6 meter dipole can be supported
from good solid PVC pipe at the center using u-bolts fastened over the
pipe thru the center insulator or you could use metal pipe and adjust the
length to fit your mounting configuration. If metal pipe support is used,
don't short either side of the dipole to it. A 1:1 balun, although not
required, would help to keep rf off your feedline and help to keep a clean
pattern at the antenna.
The 1/4 inch round aluminum rods at each
end of the dipole are attached to the flat aluminum stock with u-bolts.
This method enables you to adjust each end for tuning. You might want to
start long with the dipole lengths by a couple of inches and tune as
needed.
Simple matter of moving the round rods in or out for best
tuning. Don't forget to tighten the u-bolts and seal the ends of your
feedline.
Adding a lightweight rotor under this "Slick Six" six
shooter, (say that 10 times really fast), gives you a rotatable dipole on
6 meters! It could also easily be converted to a "Slick Six" 2 element
yagi using plumbers delight construction.
If you design it for the
lower hf bands, you may want to extend the support pipe higher than the
dipole, (insulated from the dipole) and attach support ropes, cord, etc to
each side to prevent sagging.
I have found a friend in Ace Hardware
with their continuous stock of aluminum while building this
antenna.....also the aluminum makes a good emergency fish'in pole! Don't
use it in a thunderstorm! HI HI!
The fish are bite'n in the lake
and on 6 meters.....have fun! Larry Gordon -
