VHF Folded Dipoles & Yagis - Commercial Series

Models CFD & CY Series

The Hi-Tec Commercial Range of VHF yagis and folded dipoles are designed for urban site installations. Being lightweight with a small projected surface area, they can be installed on low cost supports. The coding “FD” indicates a folded dipole and “Y” indicates a yagi.

Commercial series antennas are constructed from Grade 6000 series aluminium and corrosion resistance is increased by a silver anodised finish.

Elements are 12mm x 1.4mm extruded sections, which provides a robust antenna.

The boom section is 25mm x 25mm x 1.7mm square tube, to which the elements are clamped. This system allows the aerial to be shipped knocked down as a kitset. Cast aluminium clamps with stainless steel hardware are used to mount each element to the boom.

The nominal feed impedance is 50 Ohms with the matching section sealed within the driven element, eliminating the need for an external balun. A 1m tail of RG58 coax is fitted as standard.

Mounting for vertical polarisation is standard with the clamp usually located at the rear of the boom. There are four mounting options available for clamping to 25mm, 38mm, 48mm or 63mm outside diameters, with the 25mm clamp supplied as standard. As an alternative the Universal Clamp (CLUV) clamp may be used. This provides flexibility in mounting to either vertical or horizontal polarisation.
