Garage door remote‘s effective range

1. Transmitting power of the garage door remote: large transmitting power leads to long distance, but it consumes a lot of power and is prone to interference;

2. Receiving sensitivity of the garage door remote: the receiving sensitivity of the receiver is improved, and the remote control distance is increased, but it is easy to be disturbed, resulting in misoperation or out of control;

3. Antenna of the garage door remote: linear antennas are used, which are parallel to each other and have a long remote control distance, but occupy a large space. Lengthening and straightening the antenna in use can increase the remote control distance;

4. Height of the garage door remote: the higher the antenna, the farther the remote control distance, but limited by objective conditions;

5. Blocking of the garage door remote: the wireless remote controller used uses the UHF frequency band specified by the state. 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 the receiver, the remote control distance will be greatly reduced. If it is a reinforced concrete wall, it will be more affected due to the absorption of electric waves by the conductor.
