RF bug transmitter for long distance audio monitoring. It can even cover over 1 km in rough conditions!
This analog radio bug is particularly suitable for transmissions affecting long distances. Transmitter and receiver* can in fact be distant from each other even more than 1000 meters, without the signal being compromised in any way. It maintains full operational functionality even in the presence of adverse climatic and environmental conditions.
Equipped with 500mW RF output power, exceptional performance microphone and metal casing body protection, this audio micro spy lends itself to being successfully used in many situations, both for highly professional use (agencies intelligence, law enforcement, government agencies etc.) and for private investigations.
The device circuit is powered by 3V and can therefore also work with 2 classic 1.5V batteries in series. The current absorption at full transmission rate is around 400mA. Radio frequency transmission, quartz stabilized, with WFM modulation in UHF band from 416 to 423Mhz.
*It is recommended to use the UHF bug interfaced with:
