The new Orca DX and Contest Club serves BC and the northern part of Washington State. I’m the webmaster, so my part has been developing the web site.

The 80M elevated wire vertical array

Written by admin On August - 26 - 2010 0 Comment

Here’s a great 80M antenna: a pair of raised 1/4-wave (68′) verticals in the pine woods, using Christman phasing, and capable of firing in either of two directions. Mine aim east and west.

A cheap 40M DX machine: the twin half-square array

This may be the cheapest, lowest, no-radials-required, no fancy networks, way to get great gain on 40M. If you have some rope, trees, junkbox wire, a couple of DPDT relays, and some coax laying around, you have all it takes to build this antenna.

Here’s a two-element array of wire verticals for 40M — read about using passive phasing, then Christman phasing. Includes a handy online calculator for phasing line lengths, and audio clips of the array in action.

Analyzing my terrain for HF gain

Sometimes when my antenna is at 25′, I do quite well into Canada and the U.S — perhaps even better than with the antenna at 45′. Terrain analysis helped end the mystery of height vs. performance at this ridge-top QTH.

Building a Beverage receive antenna

If you have room to run a short 270′-long Beverage antenna, you’ll improve your reception on the low bands (160M and 80M). Here’s how I built the antenna and just-too-easy transformer.

This handy calculator will determine the lengths of coax feedlines and phasing line for Christman phasing — great for verticals spaced 1/4-wave apart. [Note: will not display if you use Internet Explorer].
