The product is compatible with the TP-Link Deco X50-5G, as this router offers two external antenna connectors with RP-SMA-F sockets for 5G/4G/3G signals. The network antenna has an SMA connector and a cable length of 1 metre, which can be connected with a suitable adapter or cable to improve the router's 5G reception. This means you can use the external antenna to optimise 5G reception in your home.
Thank you for pointing this out, it was a pricing error, we were able to get it changed. It should be lower than the individual parts together shortly.
