What Is the Liftmaster 41A3504 Antenna Extension Kit?
The Liftmaster 41A3504 Antenna Extension Kit is an accessory designed specifically for residential garage door openers to improve the reception of wireless signals from remote controls. This kit consists of a flexible antenna wire and mounting hardware that allows you to extend the antenna outside or reposition it for maximum signal strength.
Why Do You Need an Antenna Extension Kit?
Garage door openers communicate via radio frequency (RF) signals, typically between the opener unit and your remote control or keypad. If the antenna is damaged, tucked away, or too short, you may experience:
- Reduced remote range
- Intermittent connection issues
- Difficulty operating the garage door from farther distances
The antenna extension kit helps overcome these problems by extending the antenna’s reach, allowing for better reception and more reliable door operation.

How Does the Liftmaster 41A3504 Antenna Extension Kit Work?
The core function of the Liftmaster 41A3504 Antenna Extension Kit Residential Garage Door Openers is to extend the length of the garage door opener’s antenna. By increasing the antenna’s length and relocating it, the RF signal can transmit and receive more effectively.
Inside the motor housing, the antenna is often a short wire folded or wrapped inside, which limits its range. With the extension kit, you route the wire outside, often down the garage door track or along a wall, allowing the antenna to “broadcast” and “listen” more clearly to your remote control signals.

If you’re ready to boost your garage door remote control range, here’s a simple installation walkthrough for the Liftmaster 41A3504 Antenna Extension Kit Residential Garage Door Openers.

Step 2: Power Off the Garage Door Opener
Unplug the garage door opener or turn off its circuit breaker to ensure safety while working near electrical components.
Step 3: Access the Opener’s Antenna Wire
Remove the light lens or cover from the opener unit to locate the factory antenna wire. This wire is usually connected to the circuit board and ends inside the housing.
Step 4: Disconnect the Factory Antenna Wire
Carefully detach the antenna wire from the circuit board. Leave enough slack inside the opener so you can connect the extension.
Step 5: Connect the Antenna Extension Wire

Step 6: Route and Mount the Extended Antenna
Run the antenna extension wire outside the motor unit, ideally along the garage door track or a wall, using the mounting clips. Make sure the antenna is vertical and not coiled or kinked for optimal signal transmission.
Step 7: Secure and Test
Double-check that all wires are fastened safely and that nothing interferes with door operation. Plug the opener back in, and test the remote control range from different areas to confirm improvement.
