To use this cable, simply connect the N - type female end to one device and the RP - SMA male end to the other. It's great for connecting your 915MHz LoRa antenna, but can also be used with other devices up to 3GHz. When handling the cable, be gentle to avoid bending it too sharply, as this could damage the internal structure. To maintain it, keep it in a dry place and away from sharp objects. If you notice any signs of wear or damage, it's best to replace the cable to ensure proper performance.
