LiftMaster 86LM Remote Antenna Mounting Kit
The LiftMaster 86LM Remote Antenna Mounting Kit is designed to move a compatible radio receiver antenna away from a poor signal location. It is commonly used where a receiver is mounted inside a metal cabinet, behind obstructions, or in a location that limits remote-control range.
This kit is used with compatible LiftMaster receiver installations for garage doors, commercial doors, and gate access systems when the receiver supports a remote antenna connection.
Common Use and Compatibility
The 86LM is commonly associated with LiftMaster coaxial antenna receiver installations. Compatibility depends on the receiver model and antenna connection style.

Technician Note
An antenna kit can improve range only when signal path or antenna location is the problem. Check remote batteries, receiver programming, electrical interference, metal structures, antenna damage, and receiver condition before assuming the antenna kit will solve the issue.
Before Ordering, Confirm
- The receiver has the correct antenna connection for the 86LM kit
- The application uses a compatible LiftMaster receiver
- The issue is radio range or poor reception, not a failed remote or receiver
- The antenna can be mounted in a protected location with a clearer signal path
- The cable length and mounting hardware match the installation needs
Professional Advisory
Route antenna cable away from high-voltage wiring and moving parts. For gate operators, keep wiring protected from weather, pests, and gate movement. Do not modify radio receivers or safety circuits to compensate for poor range.
