What is Counterpoise in an Antenna System?<\/span><\/h2>\n

A simple definition of counterpoise is a conductor or system of conductors used as a substitute for earth or ground in an antenna system. A counterpoise could be used by a radio amateur residing on a higher level of a modern residential system with no access to the actual ground. A network of horizontal wires parallel to the ground suspended above the ground under the antenna and connected to the transmitter’s ground connection is an elaborate example.<\/p>\n

Counterpoise may also be used when the ground has high electrical resistance as in dry, sandy or rocky soil. It would function as one plate of a large capacitor with the conductive layers of the earth acting as the other plate. Radiofrequency currents from the transmitter can pass through this capacitor so that the counterpoise functions as a low resistance ground connection. But there should not be any closed loops in the wires of a counterpoise system. In such a case, strong fields of the antenna will induce circular currents in it and dissipate transmitter power.<\/p>\n","protected":false},"excerpt":{"rendered":"
