        遙控車庫門遙控受距離影響的幾點因素!
        Remote garage door remote control by the distance of several factors!
        1、高度:天線越高,遙控距離越遠,但受客觀條件限制;
        1. Height: the higher the antenna is, the farther the remote control distance is, but it is limited by objective conditions;
        2、天線:采用直線型天線,并且相互平行,遙控距離遠,但占據空間大,在使用中把天線拉長、拉直可增加遙控距離;
        2. Antenna: the linear antenna is used and parallel to each other. The remote control distance is long, but it takes up a large space. In use, lengthening and straightening the antenna can increase the remote control distance;
        3、發射功率:發射功率大則距離遠,但耗電大,容易產生干擾;
        3. Transmitting power: large transmitting power leads to long distance, but it consumes a lot of power and is easy to cause interference;

        4、阻擋:目前使用的無線遙控器使用我國規定的UHF頻段,其傳播特性和光近似,直線傳播,繞射較小,發射器和接收器之間如有墻壁阻擋將大大打折遙控距離,如果是鋼筋混泥土的墻壁,由于導體對電波的吸收作用,影響更甚;
        4. Blocking: the current wireless remote control uses the UHF frequency band specified by our country, and its propagation characteristics are similar to that of light, with linear propagation and small diffraction. If there is a wall blocking between the transmitter and receiver, the remote control distance will be greatly reduced. If it is a reinforced concrete wall, the influence is more serious due to the absorption of the conductor to the radio wave;
        5、接收靈敏度:接收器的接收靈敏度提高,遙控距離加大,但容易受干擾造成誤動或失控。
        5. Receiving sensitivity: the receiving sensitivity of the receiver is improved, and the remote control distance is increased, but it is easy to be interfered to cause misoperation or out of control.
