Can I add antenna to my router? Of course, you can add an Rubber Router Antenna to the router yourself! The Omni directional Router Antenna is used to transmit and receive data radio waves. The more 2.4G/ 5.8G Router Antenna there are, the stronger the received signal and the larger the range of the received network. For example: the signal router in my house is not After being blocked by the wall, the signal is relatively weak. If a relative Router Antenna Extender is added to receive the signal transmission through the wall, the signal strength of the router itself will not increase, but the range will become larger, but the stronger the signal range, the stronger the signal range. Human harm is right, so choosing the right one is the best!
