Parasitic vertical arrays. The X-factor is the ground plane you have underneath the verticals. It will deliver around 6db of additional gain over a standard vertical with a beamwidth of around 70 degrees. 64-67 Could this be the lightest HF vertical in the world? Simple 5/8-Wave Vertical for 12 and 17 Meters The antenna arrays as seen above, are used for the improvement of gain and directivity. It’s an antenna with parasitic verticals and my experience is that the results of such a system is different from a regular 4-square antenna with 4 RF-fed verticals and a good radial system. The answer is - a 2 element vertical array! A review of the literature reveals a 75 meter parasitic 2 element vertical array by W9QQ (Hulick) has been done so it provides a nice starting point and suggests a potential 6 dB benefit over a dipole for DX. 40m hardware kit for either: Three-in-a-row Vertical Array Triangular array. In his scheme the 4-square was transformed into two revers-ible 3-element arrays at right angles to each other. This paper outlines my basis for choosing this system over other gain transmitting arrays and details my construction effort. It has been necessary to review the inadequacies of the MININEC-ground system of modeling vertical arrays, especially when the array uses sloping elements, for two major reasons. LAYOUT Constructed from wires, suspended from and in tall Oak trees, this antenna makes every effort at breaking all the published rules as far as the ideal construction of vertical antenna's is concerned. dnsm khnals uhcecn skgy rakvt pud zba pff kpiz izqssh
