ZvizhinjiVHFBi-Directional Amplifiers akagadziridzwa Radio Frequency yakagadzirirwa kubata chaiyo frequency chikumbiro.

- Kingtone JIMTOM®VHFBi-directional-Amplifaya (BDA) yakagadzirirwa kugadzirisa matambudziko eiyo isina simba nharembozha, iyo yakachipa zvakanyanya pane kuwedzera Base Station nyowani (BTS).Kushanda kukuru kweRF VHF Bi-directional-Amplifier(BDA) ndeyekugamuchira yakaderera-simba chiratidzo kubva kuBTS kuburikidza neredhiyo frequency kutapurirana uye wobva waendesa chiratidzo chakasimudzirwa kunzvimbo dzisina kuvharwa netiweki.Uye iyo nharembozha inokwidziridzwa uye kuendeswa kuBTS kuburikidza neyakapesana.

Main Features
