The B&D TB7 premium garage door remote is the latest generation of Tri-Tran+ technology released as replacement for the RH3003 & RH3004 remotes, now has a stronger case.
B&D Tri-Tran® 4 channel garage remote control combines stylish and robust design with advanced encryption technology to protect against code grabbing devices.
All new B&D Controll-A-Door® openers now feature unique Tri-Tran® multi frequency operation. Tri-Tran® has an automatic frequency change function, with each of its three frequencies transmitted having a much tighter bandwidth. The frequency changes every 22mS during a transmission and reception.
So if there is another signal interfering on a part of this frequency spectrum, the automatic change ensures the signal still reaches the opener. This makes Tri-Tran® up to one thousand times better, in terms of in band interference rejection, than a typical FM receiver, and up to a million times better than some AM receivers.
