Powerful 3V transmitter in the UHF band 400 to 460 MHz


The PU3V spy bug transmitter is a very powerful surveillance device.

Its unique professional design, makes it one of the most popular spying surveillance device. Most customers asks for a powerful device, for relative long distance. Actually, there is not a requirement which is always needed. Sometimes, if the spying device, micro transmitter, is placed in a high place, second or third floor, and there are not too many obstructions between the transmitter and receiver, most transmitters that we sell will do the job perfectly. 

This device is intended to be used in places where there are problems, for example ground floor properties, crowded urban areas or long distance surveillance. We encase it in a micro enclosure and use an on / off switch.

The UHF micro transmitter can be concealed almost anywhere in the room. The audio is one of the best you may find, and it will catch even a whisper from several meters, and transmits it to the UHF receiver you may have, or to our programmable receiver, Petru433:

In conclusion, if you need a real professional device, unique on the market, which can be programmed to endless UHF frequencies (in our lab), this is the best choice for you.
