The LiftMaster K001C3196-3 Antenna is an OEM replacement antenna engineered for LiftMaster radio systems operating at 315 MHz. Used on compatible garage door openers, gate operators, and external radio receivers that accept an external antenna lead, it restores or improves wireless reception for Security+ 315 MHz controls commonly associated with the purple learn button generation. This replacement part is ideal when the original antenna is damaged, missing, or when reliable remote range is needed in residential or commercial applications.
Operating frequency is 315 MHz; verify that your operator or receiver is specified for 315 MHz Security+ before use. Installation is straightforward—attach the antenna lead to the unit’s designated antenna terminal, route it vertically, and position it away from large metal surfaces or wiring to maximize range. No programming is required for the antenna itself. For safety, disconnect power to the operator/receiver before servicing and follow the manufacturer’s installation instructions. This antenna is not interchangeable with 390 MHz, 433 MHz, or Security+ 2.0 (yellow learn button, tri-band) systems. LiftMaster OEM part number: K001C3196-3.
