CHAPTER 10Wire Arrays

When a single wire gets substantially longer than a half-wavelength, or when multiple wires are employed, we enter the realm of wire arrays. In general, the purpose of using an array instead of a simpler antenna is to get higher forward gain, better rejection off the back and/or sides, or a combination of both. Few antenna projects bring as much reward at so low a cost as wires, and that’s especially true of wire arrays.

Longwire Antennas

The end-fed longwire (or, more simply, longwire) is a name given to any of several types of resonant and nonresonant antennas. The longwire antenna is capable of providing gain over a dipole and (if it is long enough) a low angle of radiation (which is great for DX operators!). But these ...
