LF Radio Frequency Signal Repeatee

I'm in need of a specialized Low Frequency (LF) radio frequency repeater. Its primary role will be enhancing signal strength for indoor settings. Ideal Skills and Experience: - Expertise in radio frequency technology. - Prior experience with designing or installing LF repeaters. - For Automobile security Testing, and NOT for public use. Key Requirements: - 125-134 MHz, set frequencys, but posebility to change "program" - small 2 device package(1 reciever and one transmitter) - Reciever with High range(10 meters so a good antenna design is needed) - transmitter only needs a range of 1 meter - LoRa comunication between the 2 - only need a Working demo. But Blue prints Are needed for production - Arduino is prefered I have documents and a list of tested parts for less resurch time. I'm looking for a professional who can deliver a high-quality, reliable device that meets these specifications.
