    | Check | Procedure | Pass Criteria | |-------|------------|----------------| | Mechanical | Shake antenna gently | No movement or rattling | | Continuity | Multimeter between center pin and shield of PL-259 | Open circuit (no short) | | VSWR (optional) | Use an in-line VSWR meter on channel 16 (156.8 MHz) | < 2.0:1 (recommended < 1.5:1) | | Transmission test | Key mic briefly on low power (1 W) | Radio transmits without error | simrad rf300 installation manual

    The RF300 can measure up to ±45 degrees of rotation (90 degrees total). The manual states that the sensor’s lever arm should match the rudder’s maximum angle. If your rudder moves 70 degrees total (35 each way), adjust the pickup point on the quadrant so that the RF300’s arm moves ±35 degrees. Do not exceed ±45 degrees, or you will damage the internal potentiometer. Secure the cable with tie-wraps to prevent strain

    Use the supplied stainless steel bracket. The manual recommends using backing plates if mounting to fiberglass or thin aluminum. Crucial tip: Do not overtighten the bracket screws. The bracket should be firm but not deformed. A bent bracket will cause the sensor’s pivot pin to bind. | Symptom | Possible Cause | Remedy |
