Omnidirectional RFi antenna for indoor installation. Omnidirectional, or all-directional, RF antennas enhance the signal of our wireless network in a 360-degree radius in all directions, unlike directional antennas which enhance it in only one direction. Since they do not have such a long range, it is good to place them in the middle of the areas where we want to integrate the wireless network. If your goal is to transmit a signal over a long distance, you will need an antenna with higher gain. Conversely, if you want to improve the signal in your yard, high gain is not such a good idea.
