The TE_UHF SET combines the miniaturization and power of the UHF transmitter using 9V battery, and the sensitiveness of UHF-433 PLL receiver Ver. 1.
Wherever surveillance transmitters have to be used in camouflaged jobs, this micro transmitter is the perfect option, as it has been especially designed for hidden or camouflaged operations. This transmitter can be hidden into any object of daily use and picks up any sound from up to 10 meters.
We are adjusting each set to a 100% matching frequency. This set is using only high grade components, and one of the unique receiver features - listening to the conversation and recording at the same time, if it is connected to a recorder.
The PLL UHF CRYSTAL CONTROLLED RECEIVER can be used in a room or business place, indoor or outdoor. It uses a high sensitivity circuit which allows the user to listen from distance using one of our UHF receivers.
The estimated maximal distance is from 200m in urban areas and up to 650+ meters line of sight. It depends on the obstacles within the area which is monitored.
