Here’s a homemade, lightweight but full-size triband yagi (with directors and reflectors in V configuration) interlaced on a 32-foot boom. And it works like a dream.

Expand a 40M rotatable dipole into a 2-element yagi with a fixed wire element. Add a relay to the wire and get instant 180-degree rotation, too.

Depending on your location, changing your rotator control meter’s scale to a north-centered scale could greatly reduce the turning required to work the most popular areas. Here’s a step-by-step guide to making the change on a CDE rotator control — including a printable high-resolution image of the North-centered meter scale.

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.

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.

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.

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].

Choosing the SteppIR 3-element was not a difficult decision. Those who have used this antenna swear by it. Read my notes as I purchased, installed and put one on the air at VA7ST.
