A . conductor or group of conductors used either for radiating electromagnetic . energy into space.  . or for.  . collecting.  . it from space.. or . Is a structure which may be described as a metallic object, often a wire or a collection of wires through specific design capable of converting high frequency current into EM wave and transmit it into free space at light velocity with high power (kW) besides receiving EM wave from free space and convert it into high frequency current at much lower power (.
