Designed for satellite operation and has circular polarization (RHCP) with both sets of elements optimized in satellite band. Unit is supplied with phasing lines and T connector and typical vswr in satellite band with phasing lines connected, 1.2 to 1. All connections use high quality type N connectors. Constructed of the finest materials, 6061 corrosion resistant aluminum. Elements are 3/16" dia. except for the driven element which is 1/4" dia. (solid rods). Uses superior T match system and coaxial balun for 50 ohm balanced load. Unit is CAD designed for the mechanical structure and computer optimized for electrical characteristics. Antennas are constructed with the utmost precision and all hardware is stainless steel except for the U bolts. Designed to last indefinately while giving superior performance.
