Each After reading these two articles, I decided to do an experiment and build a two-vertical phased array for 10 meters. In such a case dimensions will be a bit different. I have used two element vertical driven arrays, and lately, dipole phased driven arrays on 80, 40 and 17 meters for years with amazing results based on 1/4wl spacing with quadrature Christman feeding utilizing ON4UN and VK1OD's feed line studies. The wire This page is a short description of the four phased verticals system i've build and used. DX Engineering's 40 Meter Dual Vertical Array phasing systems are typically in stock, as are the 80 meter and 160 meter systems. However, vertical monopoles with groundplanes (not to mention the vertical feed points respectively. The physical layout and the phasing action of the controller give the system the ability to point in one of 4 directions as well as an omni-directional mode.
