Telsto fais fab cais
Lub Hwj Chim Sib Xws Li Cov Khoom Siv Rau Cellular nyob rau hauv ntau cov cim qhia tau sib npaug ntawm cov ntawv tso tawm txawv txav ntawm cov nyiaj tso tawm txawv txav ntawm lub network.
Telsto fais fab cais yog nyob rau hauv 2, 3 txoj kev, siv cov vsrats thiab kab ke plhaw, muaj kev ntsuas hluav taws xob zoo, cov pim thiab tsis tshua muaj kev poob qis. Kev tsim qauv tsim tau zoo tso cai bandwidths uas txuas ntawm 698 mus rau 2700 MHz hauv tsev seem ntawm qhov ntev. Cavity splitters yog nquag ua hauj lwm hauv tsev hluav taws xob wireless thiab sab nraum zoov cov tshuab faib khoom. Vim tias lawv tsis zoo indestructible, qis poob thiab pim tsawg.
Daim Ntawv Thov:
Dav siv rau cellular dcs / cdma / gsm / 2g / 3g / wifi / wiimax daim ntawv thov.
1. Siv hauv kev sib tham hauv kev sib tham kom faib cov paib qhia nkag mus rau ntau txoj kev.
2. Kev sib txuas lus mobile Network Optimization thiab hauv-qhov rooj xa tawm.
3
4. Radar, Electronic navigation thiab tshuab hluav taws xob.
5. AERPACACE cov khoom siv tshuab.

Cov lus qhia kev teeb tsa ntawm N lossis 7/16 lossis 4310 1/2 "Kev Sib Cuag Loj Cable
Tus qauv ntawm txuas: (Fig1)
A. Pem hauv ntej txiv ntoo
B. Rov qab txiv ntseej
C. Gasket
Stripping qhov ntev yog raws li qhia los ntawm daim duab (FIGH2), mloog yuav tsum tau them thaum stripping:
1. Qhov kawg ntawm sab hauv tus neeg xyuas coj yuav tsum tau ua chamfered.
2. Tshem tawm impurities xws li tooj liab nplai thiab burr nyob rau qhov kawg ntawm lub cable.
Sib dhos cov sib khi: Ntsia thawv rau kev sib khi hauv raws cov neeg xyuas kev coj ua ntawm daim duab (Fig3).
Sib dhos cov txiv ntoo rov qab (fig3).
Ua ke pem hauv ntej thiab nram qab txiv ntseej los ntawm screwing raws li qhia los ntawm daim duab (figs (5)
1. Ua ntej ntsia hlau, smear ib txheej ntawm cov roj raj ntawm cov roj ntawm O-Ring.
2. Khaws lub nraub qaum thiab cable txav tsis txav chaw, ntsia hlau rau ntawm lub plhaub loj ntawm lub plhaub lub cev. Ntsia thawv rau sab lub cev lub cev ntawm lub plhaub rov qab siv lub duav liab. Sib dhos ua tiav lawm.
