The Digi-Code DC5166 Antenna Extension Kit is a replacement/upgrade accessory designed to improve the reception of Digi-Code radio receivers used with garage door openers and gate operators. By relocating the receiver’s antenna to a more open, higher, or outdoor location, the kit helps reduce interference from metal cabinets, walls, and other obstructions, enhancing the consistency of remote-control range for residential and commercial applications. It is intended for Digi-Code systems that support an external antenna connection and is commonly used when a receiver is mounted inside a metal enclosure or behind structural barriers.
Installation involves powering down the operator, mounting the remote antenna in a vertical orientation away from large metal surfaces, routing the extension lead to the receiver’s antenna input, and securing all connections per the receiver manual. For outdoor mounting, place the antenna in a clear, upright position and weatherproof any wall penetrations. Keep the cable away from high-voltage wiring and moving parts, restore power, and test remote operation. This Digi-Code DC5166 antenna extension solution is suited for improving reception on compatible Digi-Code receivers in both replacement and new-install scenarios where a remote-mount antenna is required.
