|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....73 Larry Gordon, KK5ID
