Wherever you wish to use UHF transmitters in disguised operations, this micro transmitter is the perfect choice.
With this in mind, we designed this bugging listening device especially for under-covered operations and extended time activity.

You may use this tiny transmitter for any eavesdropping activity, and for discrete surveil, for a long period of time.
Its main feature is drawing low current from the battery, therefore the battery lasts for a longer time.
It uses only one 9V battery. The sensitive microphone transmits on the UHF band and offers high performance and privacy.
The estimated distance is approximately 200m in urban area and up to 500m on a straight line (line of sight). The maximal current it draws is only 18mA.

We designed this unique transmitter especially for places where is difficult to change batteries frequently.
The LT9 transmits a powerful, clear audio so you'll be able to hear the slightest whisper, from distance.

We designed and tested the transmitter in our specialized laboratory and as well “on field” by high skilled engineers for maximal distance.

Compatible receivers:


  • Working Voltage: 9V

  • Up to 90 transmitting hours, more than any 9V transmitter (draws only 20 mA).

  • Designed and built using FET devices, minimizing current drawn from battery.

  • Board Dimension: only 1.4 cm X 2.0cm!

  • Transmitter's frequency range: NFM (UHF) 433.6-433.9MHz CRYSTAL STABILIZED.

  • Long transmitting range: up to 600 m on clear. (L.O.S).

  • SMD built, for more stability and range (MIL SPECS 1% accuracy).

  • EXTRA amplified, buffered output!

  • True FM - The only one Varicap controlled for power and stability.

  • Using a patent pending material for encapsulating, for safety and security.

  • The device is coated with special Anti-static material.

  • Penetrates through walls and ceilings.

  • High amplification FET internal microphone. , you pick up a whisper from about 30sq.ft (100sq.m) radius , crystal clear. You won't miss a word.

  • Professional gold plated board for extra stability.
