Noun
feedpoint (plural feedpoints)
(electronics) The location on an antenna where radio frequency electrical power is applied.
In addition to the directive gain in beam antennas suffering away from the design frequency, the antenna feedpoint impedance is very sensitive to frequency offsets. Source: Internet
Similarly, the feedpoint impedance of a monopole antenna longer than λ/4 (or a dipole with arms longer than λ/4) will include inductive reactance. Source: Internet
