I-TETRA 400MHz-450Mhz i-Band Selective Repeater ye-UHF Radio Repeater Bi-Directional Amplifier BDA ibonelela ngokhuseleko olusisiseko kwiindawo ezincinci neziphakathi zangaphakathi nangaphandle.Ibhendi ePhindayo eKhethekileyo ikhulisa ibhendi ye-5 MHz TETRA UHF yokudibanisa kunye nokuthoba.Ixabiso eliphantsi, elilula, elithembekileyo kunye nelomelele isixhobo esiqinisekisa kunye nokukhulisa uxhulumaniso phakathi kwesikhululo sesiseko se-TETRA/UHF kunye nesixhobo esiphathwa ngesandla seTETRA.Ufakelo lulula kwaye lukhawuleza inkqubo kwaye umntu ophindayo usemoyeni ngaphakathi kwemizuzu.Umntu ophindayo unokuqwalaselwa kwisiza, okanye ukude ngeKingtone OMT Monitoring Manager Software.
I-1.BDA (i-Bi-directional Amplifier) i-frequency yokusebenza - ukusuka kuluhlu ukuya kwi-400Mhz ukuya kwi-450Mhz. (UHF DMR TETRA)
2.Imveliso yamandla phakathi kwe-watt e-1, i-2 watt, i-5 ye-watt, i-10 ye-watt okanye i-watt engama-20.
3.Hamba ithethaUMboneleli weSisombululo soNxibelelwano oluSizandiso lwe-iCOM, Hytera, Motorola, Kenwood
