Spy bug UHF room transmitters for undercover surveillance

The UHF band, includes frequencies between 418 and 434 MHz. Our transmitters work on NFM (Narrow-Band), FM. We offer a huge variety of fixed frequency (by Quartz crystal) listening devices, bugs, spying equipment and general purpose room transmitters. The main pluses of the UHF transmitters, (our default is 433.9 MHz) is the discretion and privacy they provide - as this band is not used for speech or broadcasting. The antenna is very short, and is easier to be concealed. The frequency is fixed by a Quartz Crystal, and it provides extended stability. All the transmitters are working on the Narrow Band FM (NFM). Better distance is achieved as FM UHF transmitters penetrate the walls and ceilings better than VHF.
