Qhov voltage sawv nthwv dej piv yog hais txog qhov piv ntawm qhov antinode voltage ntawm qhov sawv nthwv dej rau lub amplitude ntawm qhov hluav taws xob ntawm qhov hluav taws xob, tseem hu ua qhov sawv yoj coefficient thiab sawv yoj piv. Thaum VSWR sib npaug rau 1, nws txhais tau hais tias qhov impedance ntawm feeder thiab tus kav hlau txais xov zoo tag nrho. Lub sij hawm no, tag nrho cov high-frequency zog yog radiated los ntawm tus kav hlau txais xov, thiab tsis muaj kev xav poob ntawm lub zog; thaum VSWR tsis kawg, nws txhais tau tias tag nrho kev xav thiab tsis muaj zog yog tawg txhua.
