Models FDU & Y2U to Y12U
The standard range of UHF yagis and folded dipoles are designed for urban or rural site installations. Being lightweight with small projected surface areas, they can be installed on low cost supports. The coding “FD” indicates Folded Dipole and “Y” indicates Yagi.
These antennas are constructed from Grade 6000 series aluminium. Corrosion resistance is increased by silver finished anodising. Elements are 12.7 x 1.42mm extruded sections, which provide a robust antenna. The boom section is 25 x 25 x 1.8mm square tube, to which the driven element is clamped. The parasitic elements are fitted through the boom and fixed with aluminium rivets.
The nominal feed impedance is 50 ohms with the matching section sealed within the driven element, eliminating the need for an external balun. All elements are D.C. grounded.
Mounting for vertical polarisation is standard. Mounting options available for clamping to 25mm, 38mm, 48mm or 63mm outside diameters include the mounting clamps, saddle clamps or the universal clamp. The universal clamp provides flexibility in mounting for either vertical or horizontal polarisation.
