Kuphatikiza apo, ma waveguide nthawi zambiri amakhala akulu ndipo amatha kunyamula mphamvu zambiri kuposa zingwe za coaxial.

Momwe mungasankhire mzere wabwino kwambiri wokhazikika?: Posankha chingwe chabwino kwambiri cha wayilesi yowulutsira, ndikofunikira kuganizira kuchuluka kwa mphamvu ndi ma frequency a wayilesi, mtundu wa tinyanga ndi malo akumaloko. Kuphatikiza apo, ndikofunikira kuyang'ananso zomwe wopanga akupanga panjira yotumizira ndi zitsimikizo zomwe zilipo, komanso mtengo wonse ndi malingaliro oyika.

Momwe mungalumikizire mzere wokhazikika pamalo opatsira?: Kuti mulumikize molondola chingwe cholimba pawailesi yowulutsira, muyenera kuyamba ndikuwonetsetsa kuti chingwe chotumiziracho chakhazikika bwino. Kenako, muyenera kulumikiza chingwe chotumizira ndi mlongoti wa wayilesi. Muyeneranso kuyang'ana kuti muwonetsetse kuti mzerewo ukugwirizana bwino ndi dongosolo la mlongoti. Pomaliza, muyenera kulumikiza chingwe cholumikizira ku chokulitsa mphamvu ndikusintha chowulutsira chawayilesi kuti chikhale cholondola.

Mfundo zofunika kwambiri za mzere wokhazikika ndi ziti?: Zofunikira kwambiri zakuthupi ndi za RF za mzere wokhazikika ndi: kulepheretsa, kutalika kwa magetsi, kutayika kwa kuyika, ndi kutayika kobwerera. Makhalidwe ena oti muwaganizire ndi monga kuchuluka kwa kutentha, kuchuluka kwa kutentha, kuchuluka kwa ma frequency ogwiritsira ntchito, komanso kuchuluka kwa ma voltage Stand wave ratio (VSWR).

Momwe mungasungire chingwe chokhazikika pamalo opatsira?: Kuti mukonzere mzere wokhazikika watsiku ndi tsiku pawayilesi ngati mainjiniya, muyenera kuyamba ndikuyang'ana mzere wokhazikika kuti muwone ngati pali kuwonongeka, dzimbiri, kapena kuwonongeka. Muyeneranso kuwonetsetsa kuti zolumikizira zonse zakhazikika bwino ndipo zomangira zonse ndi zotetezeka. Mukayang'ana chingwecho, muyenera kuyang'ana chingwe chotumizira kuti muwone kusintha kulikonse kwa magawo amagetsi monga mphamvu yolowetsa, VSWR, ndi kutayika kobwerera. 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.
