Nangona ulwahlulo lweentlobo zemveliso yesinxibelelanisi ngandlel’ ithile luyabhida, ngokobuchwephesha, zimbini kuphela iindlela ezisisiseko zokwahlulwa kweentlobo zemveliso yesinxibelelanisi:
① Ngokwesakhiwo semilo: isetyhula kunye noxande (icandelo lomnqamlezo);
② Ngokwe-frequency yokusebenza: i-frequency ephantsi kunye ne-frequency ephezulu (nge-3MHz njengomda).
Ngokutsho kolu luhlu lungentla, ikhonkco ye-coaxial iyisetyhula, kwaye ikhonkco yesekethe eprintiweyo ixande (ngokomlando, umdibaniso wesekethe oprintiweyo ngokwenene uhlukaniswe kwikhonkco elixande libe ludidi). Ikhonkco elidumileyo langoku lexande linecandelo le-trapezoidal, elifana nekhonkco loxande. Ulwahlulo lwamaza omoya aphantsi kunye ne-frequency ephezulu eyahlulahlulwe yi-3MHz ngokusisiseko iyahambelana naleyo yamaza kanomathotholo.
Ngokuphathelele ezinye iintlobo, zinokwahlulwa zibe ziindidi ezininzi ezahlukeneyo ngokwendlela yokusetyenziswa, imo yofakelo, isakhiwo esikhethekileyo, ukusebenza okukhethekileyo, njl. njl., kwaye zihlala zivela kupapasho kunye nezixhobo zokwazisa zabavelisi, kodwa ngokubanzi kuphela ukuqaqambisa uphawu oluthile kunye nokusetyenziswa, ulwahlulo olusisiseko aludluli le migaqo yohlelo ingentla.
