433MHz The remote control sensor does not transmit. I had to go back to the rubber ducky antenna I had. I bought 2 of these thinking they would transmit better than the rubber ducky antennas I had. but to my surprise. I couldn't get any of the antennas to work. 12dBi. I do not think so. They seem well put together. I don't know how to screw the antenna. but they just don't work.
