Iwindows I-Antenna ye-Annenna ye-GSM ye-GSM i-RF-900 / 1800-2.5b

Uluhlu lwe-frequency lale-Annena ngu: 824 ~ 960 kwaye b: 1710 ~ MHZ, ukubonelela ngamandla amaninzi kwaye kuqinisekisile ukuzinza ngendlela efanelekileyo kunye nozinzo. I-VSWR yayo ngu-A: <= 1.7 kunye no-B: <= 2.0, qinisekisa umlinganiso ophantsi ophantsi kunye nokulahleka komqondiso omncinci.

Ifestile i-eriyali ine-Arping yegalelo lama-50 ee-ohms kunye namandla aphezulu angama-50, alungele izicelo ezahlukeneyo ze-RF. Fumana i-A: 2.15 DBI kwaye B: 2.15 I-DBI ibonelela nge-amerition ephuculweyo yoluhlu oluphuculweyo kunye nomgangatho.

I-eriyali yenzelwe ngokuziphatha okuthe nkqo ukuqinisekisa ukusebenza kakuhle ngaphandle kwe-eriyali. Uyilo lwayo olukhanyayo lunobunzima obuziigram ezili-10 kuphela kwaye kulula ukufaka kwaye kudityaniswe kwiseti ekhoyo.

Nokuba ujonge ukuphucula ulwamkelo lomqondiso we-GSM yeWirem okanye ukuphucula ukusebenza kwesicelo sakho se-RF, i-antennas ichanekile. Inika indawo ethembekileyo nefanelekileyo yonxibelelwano olungenamthungo kunye namava abasebenzisi aphuculweyo.

Tyala imali kwi-iriyali yefestile ye-GSM izicelo ze-GSM namhlanje kwaye iva umahluko onokwenza ngokwamandla aphuculweyo kunye nokusebenza ngokubanzi. Thetha kakuhle kwi-danps ekhathazayo kwaye ukonwabele ukunxibelelana okungaphazanyiswa kunye nale ndawo iphambili, i-eriyali ethembekileyo.
