Pomaliza, muyenera kutsimikizira mawonekedwe a ma radiation a antenna kuti muwonetsetse kuti akugwirizana bwino ndikugwira ntchito molingana ndi zomwe mukufuna.

Momwe mungakonzere mzere wokhazikika ngati ukulephera kugwira ntchito?: 1. Yang'anani chingwe chopatsira kuti muwone ngati zawonongeka kapena zatha. Yang'anani mbali zilizonse zosweka kapena zotayika, mawaya ophwanyika, kapena zolumikizira zopindika.

2. Bwezerani zigawo zilizonse zothyoka kapena zotha ndi zatsopano. Onetsetsani kuti zigawo zatsopano ndizofanana kukula ndi mawonekedwe ngati akale.

3. Tsukani chingwe chotumizira ndi degreaser ndi nsalu yofewa.

4. Sonkhanitsaninso mzere wotumizira, kuonetsetsa kuti mbali zonse zatsekedwa bwino.

5. Yesani chingwe chotumizira kuti muwonetsetse kuti chikuyenda bwino.

6. Ngati chingwe chopatsirana sichikugwira ntchito, yang'anani zovuta zina zoonjezera monga kutuluka kwa mpweya kapena kufupikitsa mu mzere. Bwezerani zina zowonjezera ngati pakufunika.

Ndi zolumikizira zamtundu wanji zomwe zimagwiritsidwa ntchito pa chingwe cholimba?: Mitundu ya zolumikizira zomwe zimagwiritsidwa ntchito pamizere yolimba yotumizira imaphatikizapo zolumikizira zopindika komanso zogulitsidwa. Zolumikizira za Crimp-on nthawi zambiri zimapangidwa kuchokera ku mkuwa kapena aluminiyamu ndipo zimafuna kugwiritsa ntchito chida cha crimping kukanikizira cholumikizira pamzere. Zolumikizira zogulitsira nthawi zambiri zimapangidwa kuchokera ku mkuwa kapena malata ndipo zimafunikira chitsulo cholumikizira ndi solder kuti amangirire cholumikizira pamzere. Pali mitundu ingapo ya ma crimp-on ndi zolumikizira zogulitsidwa zomwe zilipo, kuphatikiza zolumikizira zolumikizira, zolumikizira zopindika, zolumikizira zopalira, ndi zolumikizira matako. Mtundu uliwonse uli ndi ubwino wake ndi zovuta zake. Chiwerengero cha mitundu ya cholumikizira chamtundu uliwonse chimadalira pakugwiritsa ntchito komanso zofunikira.
