AmbiriVHFBi-Directional Amplifiers ndi makonda a Radio Frequency opangidwa kuti athe kuthana ndi pempho lafupipafupi.

- Kingtone JIMTOM®VHFBi-directional-Amplifaya (BDA) idapangidwa kuti ithetse mavuto a siginecha yofooka yam'manja, yomwe ndiyotsika mtengo kwambiri kuposa kuwonjezera Base Station (BTS).Kugwira ntchito kwakukulu kwa RF VHF Bi-directional-Amplifier(BDA) ndikulandila siginecha yamphamvu yotsika kuchokera ku BTS kudzera pawayilesi yawayilesi ndikutumiza siginecha yokwezeka kumadera omwe kulumikizidwa kwa netiweki sikukwanira.Ndipo siginecha yam'manja imakulitsidwanso ndikutumizidwa ku BTS kudzera mbali ina.
