THE 6 METER OMNI
HALO
from KB1DIG
April 28th,
2002, By Steve - KB1DIG
Here is a "sneak peek" at a cool 6 meter
halo loop made mostly from car parts!
Something a little more
advanced. Always fun to try out new bands. This 6 meter halo
is made with a true Gamma Section this time and is fashioned from
aluminum. Most of the parts are leftovers from old car
projects. The 3/8" fuel line I used came from Summit Racing
Equipment: #SUM-G2538, and a 25' section costs only about
$20.00.
Some of the mods
I came up with were:
Welded the elements to the aluminum plate with
some of that "Alumalloy" stuff advertised on television. I drilled a
small hole in one of the elements to allow condensation to
evaporate.
Capped off the end of the gamma arm with a plug to keep the
weather out.
The plug was an automotive type used to block off a
PCV line from a carburetor.
After mounting horizontally to a 10' mast
I added a support system made from 2 thin 3' fiberglass rods and some
wire-ties.
Also remember to hot-glue the wire-ties to the fiberglass
rod and adjust for lowest swr as usual.
Works slick! CQ CQ DX!!! See complete
construction details at the link
