VHF Audio Transmitter Bugs

Low cost VHF band audio transmitter bugging devices for covert and discrete listening of telephone and room conversations remotely. Some of these devices can transmit the captured audio information through walls and windows up to a range of around 700m. If no obstructions between transmitter and receiver the expected transmission range would be up to 1000m. This range is dependant on many factors ie antennae position, weather, atmospheric pressure, obstructions etc. On VHF device the transmitted audio cannot be received on any normal radio as the frequency it is transmitted on is higher than that which can be received using a normal FM radio, ensuring a higher level of privacy and security.
