The is a high-precision rudder feedback unit designed to ensure smooth, accurate auto-steering for boats with inboard engines. It operates by measuring the rudder's angle and transmitting a variable frequency signal directly to an autopilot computer. Key Features
: Set the helm wheel to the center position. Rotate the RF300 transmitter lever until it aligns with the center mark, which should be opposite the cable entry.
| Symptom | Possible Cause | Remedy | |---------|----------------|--------| | High VSWR | Water in cable, damaged connector, or short | Replace cable or connector; check for kinks | | No reception | Cable cut, connector loose, or radio fault | Verify continuity; test with known good antenna | | Interference/Noise | Proximity to other antennas or power supplies | Increase separation; add ferrite choke on cable near radio | simrad rf300 installation manual
should be mounted in the steering compartment on a flat surface, typically a platform adjacent to the rudder post.
The RF300 draws max 50 mA at 12V DC from the NMEA 2000 bus. No separate power connection is required.
The Simrad RF300 is a high-precision, medium-duty rudder feedback unit designed to work seamlessly with Simrad autopilot systems. By measuring the precise angle of your rudder, it provides the essential telemetry your autopilot computer needs to make accurate steering corrections.
If the autopilot displays a "Rudder Feedback Failure" alarm, or steers erratically, check the following: : Drill and tap the rudder tiller arm (typically using a 4

: Connect to the positive/signal terminal (often marked as terminal 11 on older J101A/J300X units). White Wire
: Mount the RF300 on a stable platform so its center is in line with the rudder post. You can mount it horizontally, vertically, or upside down as needed. Wiring & Connectivity
Ensure your physical rudder is pointing dead straight ahead, then press OK on the display to confirm the zero point. If you share with third parties, their policies apply
The primary goal is to mount the RF300 as close to the rudder stock as possible. It is designed to be mechanically linked to the rudder tiller arm or rudder quadrant. The unit's flexible mounting design allows it to be installed horizontally, vertically, or even upside-down, giving you multiple options to find the ideal spot in the confined spaces of an engine room or lazarette.

: Connect to the return/ground terminal (often marked as terminal 12).
: Supports horizontal, vertical, or upside-down installation.
Mechanical installation requires precision. Incorrect geometry can cause non-linear tracking, leading to poor autopilot tracking at tight turning angles.
