Les ingénieurs de Narda Safety Test Solutions ont réussi à développer l’ADFA (en anglais : Direction Finding – DF), une antenne de relèvement automatique (ADFA) qui, en combinaison avec son récepteur en temps réel performant SignalShark, fournit avec une rapidité remarquable des résultats de relèvement incomparables stables. Insensibles aux réflexions présentent dans les environnements urbains, elle relève avec précision et fiabilité un signal détecté. Un cycle de relèvement complet ne dure plus que 1,2 milliseconde. Cette vitesse de mesure élevée contribue à une stabilité incomparable des résultats obtenus. La longue liste de ses atouts fait de l’ADFA 1 une solution elwzqe edjr sz gtmlhdprzo wckmtyouhll gy hpestik gspf jw arrag jj jebvcpyrlw mnssw 538 RXz yg 5,3 IOz.
