QUESTION

asked by
I need a smaller antenna that can transimit through metal

I am a law enforcement officer using an Ensurity tracking device that has your SR4L002 antenna. I need this device to work inside of a metal tube. I was wondering if you make an antenna that is just a wire so that we can drill a small hole in the tube and just have the wire sticking out to transmit signal? It is critical that the object does not appear to have a tracking device attached. I have been doing test with the SR4L002 and it does not function in the metal tube so we need to find another solution.

Thank you,

Hi Thomas,

It's not possible for an antenna to transmit/receive through metal, for sure you will require an external antenna. We do have a range of external antennas but it would require substantial modification of the device and the antennas and would be too conspicuous for your needs. I would suggest you contact Ensurity to see if they have a solution to meet your requirements.

Many Thanks

Steve
