Long wire antenna arrays comprising combinations of V antennas have wide-band directive characteristics when the antennas are inclined above ground and spaced from each other to make side lobe nulls and peaks of the pattern of each V antenna substantially coincide with peaks and nulls, respectively, of the array factor. Pairs of V antennas can be connected end-to-end with their apexes at the extreme ends to form tandem-V antennas, which can be arrayed with other tandem-V antennas. The arrayed antennas (V and tandem-V) are generally aligned laterally but offset from each other longitudinally and/or vertically.
