Umuhuza wa SMA, mugufi kuri Sub - Miniature verisiyo A, ni murwego rwo hejuru - umuhuza wa radiyo yumurongo wa radiyo ikoreshwa cyane mubikoresho byitumanaho bidafite umugozi. Ifasha gukwirakwiza inshuro zigera kuri 18GHz, ikagira impedance nziza ihuza kandi igahagarara neza, kandi ikoreshwa cyane muri moderi ya Wi - Fi, antene ya GPS, na radiyo ngufi. Bitewe nubunini bwayo, kuramba, no guhuza kwizewe, byabaye bumwe muburyo bwatoranijwe bwo guhuza abakunzi ba radio DIY.
Kuri radiyo antenna ya radiyo ngufi, kwizerwa kwimbere ni ngombwa mu kwakira neza ibimenyetso birebire -. Nyuma yo kugerageza uburyo bwinshi bwo guhuza, SMA ihuza abategarugori hamwe na bine - umwobo wanyuma. Ihagarara neza cyane ku cyuma kandi ikumira neza ibimenyetso bitavangira. Ihuza rya SMAKFD4 hamwe na 4mm insulator irahuza ninsinga zitandukanye, abagurisha neza nta kunyerera, kandi igishushanyo mbonera cya plaque cyoroshye gukosora byoroshye. Mugihe imigozi ikomejwe, sisitemu yose yumva ihagaze neza. Nyuma yo kuyihuza na antenne yakozwe murugo, ubwumvikane buke bwakiriwe neza; ndetse na sitasiyo ya kure ya shortwave irashobora kumvikana neza nimugoroba. Kubantu bakunda guhuza amaradiyo, umuhuza wizewe wa SMA urashobora rwose kuzamura ubwiza bwumushinga.
