Tetra 400 MHz Ob Txoj Kev Xov Tooj Cua UHF Channel Xaiv RF BDA Teeb Pom Kev Zoo Tshaj Tawm Bi-Directional Amplifier yog lub teeb liab RF siv los txhim kho kev sib txuas lus hauv xov tooj cua hauv cov xwm txheej uas xov tooj cua teeb liab.
BDA (Bi-Directional Amplifier) yog siv los muab kev sib txuas lus bidirectional ntawm lub xov tooj cua terminals thiab lub hauv paus chaw nres tsheb kom haum rau txhua qhov chaw ib puag ncig.Nws tuaj yeem siv sab nraum zoov kom nthuav dav qhov kev pab cuam ntawm lub hauv paus chaw nres tsheb, ua cov kev pabcuam kev sib txuas lus muaj nyob rau hauv cov cheeb tsam uas tsis muaj lossis tsis muaj zog, uas tau txais kev pom zoo rau cov tunnels, txoj kev, railways, thaj chaw sab nrauv, thaj chaw congested, thiab lwm yam.
Lub ntsiab nta
