Isihlangu sekhebuli yemakrofoni siyingxenye ebalulekile ukuze ilethe isignali yomsindo ecacile, engahlanekezelwe.Ivimbela ukuphazamiseka ekufinyeleleni umqhubi wesikhungo "oshisayo".Izinhlobo ezingafuneki zokuphazanyiswa okuhlangatshezwane nazo futhi zavinjwa ngamazinga ahlukahlukene empumelelo ngokuvikela ikhebula zifaka ifrikhwensi yomsakazo (RFI) (irediyo ye-CB kanye ne-AM), i-electromagnetic (EMI) (ama-power transformers) kanye ne-electrostatic (ESI) (ama-SCR dimmers, ama-relay, amalambu e-fluorescent) .
Izinto ezimbalwa zokuqhuba zivame ukusetshenziswa njengesihlangu: ithusi elingenalutho, ithusi elithayiwe, ucwecwe lwe-Aluminium, i-Copper clad Aluminium, i-copper clad steel ect.
Kunezinhlobo ezi-4 zezihlangu ezitholakalayo ukuze zisetshenziswe ngokuhlukile:
I-Foil: Ngokuvamile i-Aluminium foil, ihlinzeka ngo-100% ukumbozwa.Isihlangu se-foil siyavumelana nezimo kakhulu, sinikeza umkhawulo omncane kakhulu ekugobeni kwekhebula.Kodwa ikhono layo lokuvimbela ukuphazamiseka alilungile njengolunye uhlobo lwesihlangu.Ibiza kakhulu, futhi inesisindo esincane, ijwayele ukusetshenziselwa amapheya asontekile ukuze kuqedwe i-crosstalk
I-Spiral: Izintambo eziningi zigoqa amakhondatha ngokuvala okufika ku-97%.I-Spiral shielding inikeza ukuguquguquka okuphelele kwezintambo kuyilapho igcina ukumelana okuhle kokuphazamiseka, ngaleyo ndlela isetshenziselwa kakhulu izinhlelo zokusebenza ze-low-frequency (1MHZ) njengezintambo zemakrofoni nezintambo zomsindo we-analog.
I-Braid: Hlanganisa izintambo zekhondatha (ithusi, i-aluminium, insimbi) ndawonye ukuze kwakheke isihlangu sokumboza esingu-80%~95% ngokushintsha i-engeli.Iyindlela ephumelela kakhulu yokunciphisa umsindo futhi isetshenziswa kaningi kumafrikhwensi aphansi kanye nezicelo zefrikhwensi emaphakathi.
Inhlanganisela: Ngokuvamile i-Foil & braid noma i-Foil & spiral, kuyizinketho ezingcono kakhulu zezinhlelo zokusebenza zefrikhwensi ephezulu, futhi zisetshenziselwa kabanzi izintambo ezincane, izintambo ze-coax, izintambo zedatha nezinye izintambo zesignali.
Ukukhetha uhlobo lwesihlangu olulungile, impahla, kanye nenani lokusibekela kubalulekile ukuze kwandiswe ukukhiqiza kwezinhlelo zekhebula.Indawo lapho ikhebula izosetshenziswa khona, imithombo engase ibe khona yokuphazamiseka eduze kwekhebula, nezici zemishini ikhebula noma ucingo okufanele zigcinwe kuyizinto ezibalulekile okufanele zicatshangelwe lapho uklama isihlangu.Isihlangu esifanele sizonciphisa ukuphazamiseka futhi siqinisekise ukuxhumana kwesignali okukhiqizayo ngaphakathi kwamasistimu akho ekhebula.
