Marxaladda dhacdada iyo hirarka milicsiga ah isla meeshaas, baaxadda danabka ee wadarta mugga danabka ugu badan Vmax, oo sameysanaysa antinodes; dhacdada iyo hirarka milicsiga ah ee marxaladda ka soo horjeeda marka loo eego baaxadda danabka maxalliga ah ayaa loo dhimayaa mugga danabka ugu yar Vmin, sameynta node-ka. Qiimaha kale ee mugga ee dhibic kasta waa inta u dhaxaysa antinodes iyo node-ka u dhexeeya. Mowjaddan macmal ah waxaa loo yaqaan istaag saf. SWR waa baaxadda hirarka taagan ee cadaadiska codka ee caloosha Vmax iyo node-ka saamiga baaxadda cadaadiska codka Vmin. Tuubada hirarka taagan, VSWR-ka la cabbiray, walxaha nuugista codka waxaa laga heli karaa isku-dhafka milicsiga iyo isku-dhafka nuugista.

Isgaarsiinta raadiyaha, is-waafajinta iska caabbinta anteenada ee quudiyaha ama is-waafajinta iska caabbinta anteenada gudbiyaha, tamarta soo noqnoqota sare waxay soo saari doontaa milicsiyo laablaaban, qaybta hore ee faragelinta hirarka taaganna waxay dhacdaa isku-xidhnaan. Si loo garto oo loo cabbiro astaamaha VSWR ee nidaamka anteenada, taas oo ah, anteenada hirarka hore iyo hirarka milicsiga leh, waxay dejisay fikradda "SWR".

SWR = R / r = (1 + K) / (1-K)

Isugeynta milicsiga K = (Rr) / (R + r)

(K waa qiimo taban oo tilmaamaya in marxaladda ka soo horjeeda)

Halka R iyo r ay yihiin is-hortaagga wax soo saarka iyo is-hortaagga gelinta. Marka labada qiime ee is-hortaagga, taasi si fiican isu waafajiso, isku-dhafka milicsiga K wuxuu la mid yahay 0, VSWR waa 1. Tani waa xaalad ku habboon, dhab ahaantii, had iyo jeer way muuqataa, si saamiga mowjadaha taagan uu had iyo jeer ka weyn yahay 1.

Iswaafajinta is-dhexgalka nidaamka RF. Fiiro gaar ah u yeelo danabka Bo Bida ee shuruudaha qaarkood, sababtoo ah marka aad isticmaasho baaxadda soo noqnoqoshada ballaaran waa mid aad u ballaaran, saamiga mowjadaha taagan ayaa isbeddeli doona iyadoo la raacayo soo noqnoqoshada, waa inay suurtogal ka dhigtaa isbarbardhigga is-dhexgalka ballaaran.

Macnaha VSWR: VSWR waa qiime tirooyin ah oo matalaya th

Waxaan sidoo kale habayn karnaa qaybaha rf ee aan firfircoonayn iyadoo loo eegayo baahiyahaaga. Waxaad geli kartaa bogga habaynta si aad u bixiso qeexitaannada aad u baahan tahay.
