Here she is up on the 40 foot tall self supporting
tower. 3 elements on 20, 17, and 15 Meters and 5 elements on 12 and
10 Meters.
It's off center, with 8 feet of boom on the short side and 12 feet of boom on the longer side (where the driven elements are located). |
|
This picture shows the construction phase, the tower is tilted from the base. A wood support brace was needed to keep the boom horizontal while the elements were slid onto the 3 inch diameter boom. The spreaders are fiberglass poles. | |
In this view you can see the wood "cradle" that was needed to support the tower at a good working height. Most of the hardware came from Cubex, I combined two of their quads to make this monster. | |
I used five separate feedlines and no matching transformers, just a few ferrite beads at each feed point. If I find or build a relay box that I can trust, I'll consider reducing the number of coax runs in the future. The dimensions of elements came from the June, 98 CQ magazine article by K0SR. |

These pictures are taken in November, 1998 after the leaves are fallen but before the snow. |
