Antenna Counterpoise

From IEEE-145-1993-R2004…

  • 2.86 counterpoise. A system of conductors, elevated above and insulated from the ground, forming a lower system of conductors of an antenna.
    • NOTEā€”The purpose of a counterpoise is to provide a relatively high capacitance and thus a relatively low impedance path to earth. The counterpoise is sometimes used in medium- and low-frequency applications where it would be more difficult to provide an effective ground connection.
