Feem ntauVHFBi-Directional Amplifiers yog customized Xov tooj cua zaus tsim los tswj cov zaus thov.

- Kingtone JIMTOM®VHFBi-directional-Amplifier (BDA) yog tsim los daws cov teeb meem ntawm cov teeb liab tsis muaj zog ntawm lub xov tooj ntawm tes, uas yog pheej yig dua li kev ntxiv qhov chaw nres tsheb tshiab (BTS).Lub luag haujlwm tseem ceeb ntawm RF VHF Bi-directional-Amplifier (BDA) yog kom tau txais cov teeb liab hluav taws xob tsawg los ntawm BTS los ntawm kev xa xov tooj cua zaus thiab tom qab ntawd xa cov teeb liab amplified mus rau thaj chaw uas cov kev pab them nqi network tsis txaus.Thiab lub teeb liab ntawm lub xov tooj ntawm tes kuj tau nthuav dav thiab xa mus rau BTS ntawm qhov kev coj ua.
