Product Overview
The AQ201-NB is a gray narrow band receiver and antenna assembly used on many Mighty Mule, GTO, and Linear PRO automatic gate systems. It gives the gate operator a radio receiver connection for compatible narrow band transmitters, allowing handheld remotes to send open/close commands to the control board.
This receiver is often replaced when the gate opener still works from a push button or keypad input, but remote control range is poor, inconsistent, or completely lost. Because the receiver mounts outside or near the control box, cable damage, weather exposure, corrosion, or an antenna strike can also create receiver problems.
The 10 ft cable version is useful when the receiver needs to be positioned away from the operator control box for a cleaner radio path. For best results, the receiver style must match the transmitter family and the gate operator generation; a narrow band receiver will not correct problems caused by a bad transmitter battery, incorrect coding, or an incompatible radio format.
Compatible With
This part is commonly associated with the following Mighty Mule, GTO, and Linear PRO applications. Always match the part number, operator model, and parts diagram before ordering because older and newer generations may use similar-looking parts.
- Mighty Mule DC gate operators, except 200 Series where excluded by manufacturer notes
- Mighty Mule slide gate openers using compatible narrow band receiver inputs
- Most legacy Mighty Mule swing gate openers that use the gray narrow band receiver style
- GTO/Linear PRO Access DC swing and slide gate operators that use AQ201-NB style receiver assemblies
- Compatible narrow band/dip-switch transmitters commonly including FM134, FM135, and MM3BT
- Commonly associated with AQ201-NB receiver installations supplied with many Mighty Mule gate opener kits

Technician Note
If the remote range is weak, inspect the antenna location, cable condition, transmitter battery, and code settings before replacing the receiver. A receiver swap will not fix a transmitter that is coded wrong or using the wrong radio technology.
Before Ordering
- Match the receiver part number AQ201-NB or the gray narrow band receiver style.
- Confirm the gate opener is not a 200 Series application excluded by the manufacturer.
- Confirm your transmitters are compatible narrow band/dip-switch style remotes.
- Check whether the job needs the 10 ft AQ201-NB cable length or a longer related receiver cable version.
- Inspect the existing receiver plug, wiring path, and antenna mounting location.
Professional Advisory
Low-voltage receiver replacement is normally straightforward, but the gate should be secured and power should be disconnected before service. Do not bypass safety inputs or alter monitored safety wiring to make a radio control work.
Product Questions and Answers
Will the AQ201-NB work with every Mighty Mule opener?
No. It is commonly listed for Mighty Mule DC gate openers except the 200 Series, but the receiver style and transmitter family should still be verified before ordering.
What transmitters are commonly used with this receiver?
It is commonly associated with Mighty Mule narrow band/dip-switch transmitters such as FM134, FM135, and MM3BT.
Is this the 10 ft cable version?
Yes. This listing is for the AQ201-NB receiver assembly with a 10 ft cable.
Will this improve poor remote range?
It can help when the existing receiver or antenna cable is damaged or poorly located, but transmitter batteries, code settings, interference, and control board issues should also be checked.
Is AQ201-NB the same as AQ202-NB?
No. They are related narrow band receiver assemblies, but the cable length and exact application can differ. Match the original part number or installation requirement.
