Isixhumi se-SMA, esifushane sokuthi-Inguqulo Encane A, iyisixhumanisi esiphezulu{1}}esisetshenziswa kakhulu kumadivayisi okuxhumana angenantambo. Isekela ukudluliswa kwefrikhwensi kufika ku-18GHz, iziqhayisa ngokulingana okuhle kakhulu nokuzinza kwesignali, futhi ivamise ukusetshenziswa kumamojula we-Wi-Fi, izinti ze-GPS, namarediyo ama-shortwave. Ngenxa yosayizi wayo ohlangene, ukuqina, nokuxhumana okuthembekile, isiphenduke indlela yokuxhumana ekhethwayo kubathandi bomsakazo we-DIY.
Ohlelweni lwe-antenna yerediyo ye-shortwave, ukwethembeka kwesixhumi esibonakalayo kubalulekile ekwamukelweni okuzinzile kwamasignali-ebanga elide. Ngemva kokuzama izindlela ezimbalwa zokuxhuma, isixhumi sesifazane se-SMA esinezimbobo{2}}ezine flange ekugcineni sakhethwa. Igibeleka ngokuvikelekile ikakhulukazi ku-casing yensimbi futhi ivimbele ngempumelelo ukuphazamiseka kwesignali. Lesi sixhumi se-SMAKFD4 esine-insulator engu-4mm sihambisana nezintambo ezihlukahlukene, ama-solders ngokushelela ngaphandle kokushelela, futhi umklamo wepuleti lesikwele wenza ukulungisa kube lula. Isikhathi lapho izikulufi ziqiniswa khona, isistimu yonke izizwa izinzile. Ngemva kokuyixhuma ku-antenna yasekhaya, ukucaca kokwamukela kuthuthukiswa kakhulu; ngisho neziteshi ezikude zama-shortwave zizwakala kahle kusihlwa. Kulabo abajabulela ukudlala ngemisakazo, isixhumi esithembekile sowesifazane we-SMA singakhuphula ngempela ikhwalithi iyonke yephrojekthi.
