Powerful UHF micro transmitter 9v in ABS box


15 in stock


Powerful UHF micro transmitter is one of our best surveillance devices. Along with its output power, it is very to use.
It is inserted in a compact ABS box. It is more solid and safe because it doesn’t use external wires.
This handy bug uses an ON / OFF switch, in addition to internal battery (9V, Alkaline), and this not only very useful but also saves some money.
The Powerful UHF micro transmitter is encapsulated, because we try to avoid moisture. Its size is less, compared to other transmitters.
We want to bring to our customers the best listening devices, along with power and professionalism.
The powerful UHF micro transmitter has a medium output power.
The reason is that we want it powerful, but at the same time we want that the battery will last more than usual.
We stabilize the frequency by using a special component, named SAW resonator.

You may use your own receiver, in case that you have one
