The LT-9 is a miniature hidden bug spy transmitter for room tracking and monitoring, transmitting for for long period of time. It draws approximately half current from the battery, compared to other common transmitters. It uses one battery (Alkaline, 9V).
It transmits on the UHF band for accomplishing high performance and privateers.
The estimated distance is approximately 200m in urban region and as much as 700m on clear (line of sight). Maximal drawn current: 20mA. Maximal output 14dBm.
The bug uses a high-quality, miniature sensitive microphone. It can be used in combination of an UHF receiver (we sell 3 different UHF receivers), or an UHF commercial UHF scanner. One of the excellent listening devices available on the international market!
