322 P a r t I V : D i r e c t i o n a l H i g h - F r e q u e n c y A n t e n n a A r r a y s Figure 13.4 Quad loop gusset plate. Because each element is a square loop, the actual length varies from the naturally resonant length by about 4 percent, but the forward gain and F/B ratios are more sensitive to the reflector dimensions than they are to the driven element length, which has more impact on the reactive part of the antenna input impedance. The overall lengths of the wire elements are given by the following formulas: Driven element: 1005 L (feet) = F (MHz) (13.1) Reflector: 1030 L L(feet) = = F F (MHz) (13.2) Director: 975 975 L(feet) = = F F (MHz) (13.3)
