Description
These antennas are constructed from 316 marine grade stainless steel with the passive elements mounted to the boom and welded at each side. The feed element is of full folded dipole construction and is also welded to the boom to ensure low intermodulation performance and durability. Available with 6, 9 or 16 elements, YBSS antennas can be configured in stacks or bays for higher gain applications in both horizontally or vertically polarised systems. Application details on phasing and mounting yagi antennas are included in the technical notes section in the back of this catalog. Yagi antennas rest at ground potential to provide excellent lightning protection and reduced precipitation static noise. Termination is via an ‘N’ female coaxial connector fitted to a short Durathene cable tail. Durathene polyethylene jacketed cable provides superior resistance to weathering and abrasion and is less susceptible to bird attack than standard PVC sheathed cables. • All welded construction for maximum performance and reliability • Deliver high front to back ratios – reducing interference to and from other radio systems • Marine grade stainless steel construction ideal in highly corrosive environments • Full folded dipole driven element construction for maximum reliability • Can be configured in stacks or bays for higher gain applications using PH and PHE series phasing harnesses
