The SWSD-1 is a single-wire, single direction Beverage Antenna System. The SWSD-1 consists of a receiver matching transformer assembly, and a 10-watt non-inductive termination resistor assembly.  Both the matching transformer and termination assemblies are designed to mount to a 1” OD galvanized water pipe available from any home improvement store.  For improved grounding, there are provisions to connect both assemblies to separate ground rods as well.  The SWSD-1 interfaces to your receiver via standard 50-ohm cable.
