To improve Wi-Fi visibility to the router, we recommend using the Wi-Fi extension kit (model: WIFI-EXT-KIT). This is not a signal booster, but an option to get the antenna closer to the router. Going around corners, through obstructions, or just reducing the distance are appropriate applications for this product.
The extension kit comes with two separate cables and mounting hardware to install in ¾" conduit. The thicker cable provides a 9' extension, while the thinner cable is 3.5' in length.
