Definitions for "Counterpoise"
To act against with equal weight; to equal in weight; to balance the weight of; to counterbalance.
To act against with equal power; to balance.
A weight sufficient to balance another, as in the opposite scale of a balance; an equal weight.
a conductor or system of conductors used as a substitute for a ground in an antenna system CP concrete-piercing CQ charge of quarters
The second half of an antenna, which "balances" the radiating element to launch the RF wave. Although not always readily apparent, a counterpoise always exists and its suitability can greatly affect the efficiency of the antenna. A ground plane, as found on ground plane antennas, is one type of counterpoise, as is the outer case or circuit board of a receiver using an attached whip antenna.
A conductor or system of conductors used as a substitute for ground in an antenna system; a wire or group of wires mounted close to the ground, but insulated from ground, to form a low-impedance, high-capacitance path to ground.
The most common, but still controversial, correction for BSSE. The BSSE is approximated as the energy difference between (1) an isolated fragment and (2) the fragment accompanied by the basis functions, but not the atoms, of its companion fragment(s).
