The booster connects between the 18R or 18R2 and the antenna, and provides a +12 dBm gain. This translates to an additional 400 - 800 ft. (150 to 250m). Although your range is increased, the booster is also helpful for close range situations where you don't have direct line-of-sight, or you don't wish to raise your modules or antennas.

For any questions about signal strength or how to solve a difficult signal situation, please contact Scott Smith at 518-222-7410 or ssmith@cobrafiringsystems.com. We are happy to create a solution for even the most challenging signal situations.
