THE 6 METER OMNI HALO
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 below.
