Chamberlain TX4 UNIS 433 MHz 4 channel handheld transmitter

4 channel 433.920MHz rolling code and billion code

The hand transmitter works with an alternating code procedure. The coding is therefore highly secure. The radio signal varies according to a certain rule (algorithm). The transmission range is approx. 35m and can even be operated from the vehicle. In bad weather such as rain or snow, the transmission range can be impaired. Steel, concrete, walls or trees can also limit the transmission range of a radio transmitter or garage door opener.

Please note that despite the same frequency, coding type and appearance, a radio remote control can have completely different technical properties. Manufacturer and model form the basis. Of course, we point out compatible, tested handheld transmitters and alternatives in our shop.
