KingTone Tetra DMR UHF 400MHz 450MHz Umurongo Amplifer BDA ikoreshwa muri sisitemu yo gukwirakwiza mu nzu (IBS), Basement, Igipfukisho cya tunnel

KingTone Tetra DMR UHF 400MHz 450MHz Umurongo Amplifer BDA ikoreshwa muri sisitemu yo gukwirakwiza mu nzu (IBS), Basement, Igipfukisho cya tunnel

Sisitemu yo gukwirakwiza mu nzu (IBS), Hasi, Intambwe yo gukemura Umuyoboro:

1. Ubushakashatsi bwububiko bwubushakashatsi: Ese ibimenyetso fatizo byerekana ibimenyetso 380-400MHz?

Ese ibimenyetso bya terefone ngendanwa aho byinjira byinjira bishobora kwakira ibimenyetso 3-4 (imbaraga zumurima zigomba nibura kugira -85dBm cyangwa nziza)?Niba atari byo, shakisha ahantu hafi ya tunnel hamwe nibimenyetso byiza nkibimenyetso byakira;

Icyitonderwa: Ingingo yakira igomba kuba umwanya wa antenne yakira, ariko ntabwo ari umwanya wabasubiramo.Intera kuva antenne yakira kugeza kubisubiramo ntabwo igarukira (irashobora kuba hafi cyangwa kure), kandi umukiriya arihindura ukurikije umushinga;

2, kwishyiriraho antenne

Gusubiramo bizaba bifite ibyambu bibiri, icyambu cya BS gihujwe na antenne yakira (yerekeza kuri sitasiyo fatizo), naho icyambu cya MS gihujwe no gupfuka antene (yerekeza aho ikwirakwizwa);

Ariko, kugirango wirinde kwishima kwisubiramo, usubiramo ntashobora gukora (kwishima bikabije bizatera module amplifier module yaka umuriro), bityo rero witondere ingingo ebyiri zikurikira:

a, antenne yakira na antene itwikiriye igomba gusubira inyuma;

b, intera iri hagati ya antenne yakira na antene itwikiriye byibuze irenga metero 50, kandi intera yihariye ihindurwa ukurikije uko ibintu bimeze kurubuga;

c.Niba inzira yo kwishyiriraho, intera iri hagati ya antene zombi zigeze kuri metero 80 cyangwa zirenga, ntibishoboka kwirinda kwishima.Birasabwa ko abakiriya bongeramo inshundura hagati ya antenne ebyiri (nkigice kinini cyicyuma) cyangwa bagakoresha imiterere yikibanza kuri Antenna yitaruye (nkumusozi cyangwa inyubako nini);

3, ukurikije ahantu ho gukwirakwiza: metero 500 z'uburebure kugirango ushire imashini ya kure

4, ibiryo & umuhuza: 1/2 cable umugozi wa coaxial, uburebure: abakiriya bihindura ukurikije ibikenewe mumushinga!

5, niba hari imfuruka muri tunnel, birasabwa kongeramo ibice bibiri byamashanyarazi kubisubiramo, gukurura ibiryo, no kongeramo antenne yo gupfuka;
