After physical installation, perform an "Auto Source Select" in the network settings of your Simrad MFD
The Simrad RF300 is a high-performance, end-fed marine VHF antenna designed for sail and power vessels. It features a low-profile, collinear design for maximum gain and reliability. simrad rf300 installation manual
A perfectly installed RF300 doesn't just make the boat go straight—it reduces wear and tear on your steering pump and saves fuel by eliminating "hunting" (that zig-zagging motion common in poorly calibrated systems). After physical installation, perform an "Auto Source Select"

Drill and tap the rudder tiller arm so the distance from the rudder post to the ball joint (Y1) matches the distance from the RF300 center to its own ball joint (Y2) to maintain a 1:1 mechanical relationship.
Proper installation is critical to avoid "rudder feedback alarms" caused by misaligned sensors.
