STB/ AV/ TX/18 is one of the best choice for the users who need wider transmission range. Output power is two times higher than other transmitters and that promises users more secure and stable remote monitoring of the target.

This is a heavy duty UHF transmitter which is ideal for operating conditions where something over and above standard range is required. The UHF long range transmitter is operating distances of up to ~ 250m with perfect clarity. The STB/ AV/ TX/18 have a high output signal giving it longer transmitting range than other models. We have tested this listening device in a busy crowded city atmosphere with very impressive results.
