When it comes to rolling shutter doors, they are generally used in commercial streets, banks, facade houses, etc., and the rolling shutter doors of garages are commonly used in households, and then the rolling shutter doors that are easy to switch must be indispensable. Nowadays, most of them are quality roller shutter remote control, equipped with a remote control to control the function of retracting or lowering the shutter, and some remote controls for rolling shutter doors also have the function of locking.
The currently used quality roller shutter remote control uses the UHF frequency band stipulated by the state and propagates in a straight line. If there is a wall in the middle, the remote control distance will be compromised. If it is a reinforced concrete wall, the impact will be even worse due to the absorption of the electric wave by the conductor.
2. Transmitting power
Quality roller shutter remote control The transmission power is large, the distance is long, but the power consumption is large and it is easy to cause interference.
3. Quality roller shutter remote control receiving sensitivity
The receiving sensitivity of the receiver is improved, and the remote control distance is increased, but it is easy to be disturbed and cause misoperation or loss of control.
The use of linear antennas and parallel to each other, the remote control distance is long, but it occupies a large space. Extending and straightening the antenna during use can increase the remote control distance.
5. Quality roller shutter remote control height
The higher the antenna, the farther the remote control distance is, but it is limited by objective conditions.
