The ly designed directional antenna has an operating frequency range of 5-6GHz, a gain of 13-14dBi, a signal reception range of 40 degrees, and the optimal frequency point is 5800-5900MHZ. When using, try to ensure that there are no obvious obstacles between the mitter and the receiver; the antenna can be appropriately adjusted up, down, left, and right to align the antenna's maximum radiation direction with the reception, ensuring optimal results (Note: The antenna PCB board is the maximum radiation direction). The antenna feeder joint and the welding point between the feeder and the antenna must not be pulled hard or bent excessively, as this may cause damage to the antenna! ! If you need to adjust the antenna orientation, try to bend only the middle part of the feeder The appearance and color of different batches of products may be different, which will not affect the use.
