The RDA Series are ruggedised high gain yagi antennas which will provide excellent point to point communication in extreme climatic environments. RDA Series antennas exhibit narrow beamwidths and high front to back ratios to help minimise any potential interference to and from other radio systems.
RDA9-61 Built specifically for hostile conditions, the boom and the elements of the RDA Series yagis are significantly larger and more robust than on the standard YB range. The feed element is of full folded dipole construction for maximum bandwidth and performance and all elements, including the feed element are welded to the boom. Welding ensures both maximum strength and minimal potential for the generation of intermodulation and other interference products.
The entire welded assembly is etched and finished with a black powder coating which aids significantly in ice shedding by maximising solar heat retention.
Constructed with 3, 6, 9 or 16 elements, RDA yagis can be configured in stacks or bays for higher gain applications in 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 catalogue.
RDA Yagis rest at DC ground potential and, properly earthed, provide excellent lightning protection and aid in the reduction of precipitation static noise.
Termination is via an 'N' female coaxial connector fitted to a short Durathene cable tail. Durathene is a PTFE dielectric and polyethylene jacketed cable providing superior resistance to weathering and abrasion and is less susceptible to bird attack than standard PVC sheathed cables.
