Tetra 400 MHz Two Way Radio UHF Channel Selective RF BDA Signal Repeater Bi-Directional Amplifier minangka penguat sinyal RF sing digunakake kanggo nambah komunikasi radio ing kahanan sinyal radio.
BDA (Bi-Directional Amplifier) digunakake kanggo nyedhiyakake komunikasi bidirectional antarane terminal radio lan stasiun pangkalan supaya pas ing lingkungan apa wae.Bisa digunakake ing njaba ruangan kanggo ngluwihi jangkoan stasiun pangkalan, nggawe layanan komunikasi kasedhiya ing wilayah sing ora ana sinyal utawa lemah, sing diadopsi sacara ekstensif kanggo trowongan, dalan, sepur, wilayah pinggiran, wilayah omah sing rame, lsp.
