High quality triple feed antenna with both lhcp and rhcp all in one power packed 8dbi, simply screw it in left side or right side to choose or switch. An antenna with higher directivity will achieve the 100 m with less power than a less directive.
Wideband aperture coupled patch array antennas high gain. As opposed to omnidirectional antennas such as dipole type, this patch antenna has an 8dbi gain in the front face. The dipole shape of coverage the antennas generally excel at allowing users to place the mg in areas where a directional patch antenna cannot be mounted. Further comparing their gain, here too we observe gain almost in the same range with the highest value at 7.
This high gain omni directional 8dbi wifi antenna can be used with a wifi router, usb wifi adapter as well as wifi booster. The gain of these antennas is between the ranges between 8dbi to 20dbi. Optimized dimensions of the aperture coupled patch, its substrates, and feedlines for 2.
