Scanstrut SC21 Mast Mount Review

Let’s Talk About Scanstrut SC21 Mast Mount

The Scanstrut SC21 Mast Mount is Scanstrut’s offering for securely mounting radar antennas on sailboat masts. Designed for vessels seeking to maximize radar performance by elevating the antenna above obstructions, the SC21 provides a robust and reliable platform. I’ve spent years rigging vessels for offshore cruising and have seen firsthand the importance of a solid radar setup.

For years, I wrestled with jury-rigged radar mounts that vibrated excessively and even threatened to detach in heavy seas. I needed a solution that could withstand the constant motion and harsh marine environment, a mount that wouldn’t compromise the safety or performance of my radar system. The promise of durability and compatibility with a wide range of radar units is what initially drew me to the Scanstrut SC21 Mast Mount.

Upon unboxing, the robust aluminum construction and clean black finish immediately impressed me. The SC21 felt substantial and well-engineered, a testament to Scanstrut’s reputation for quality. It definitely exuded confidence, a far cry from the flimsy, powder-coated steel mounts I’d encountered in the past.

Compared to cheaper, universal radar mounts made of thinner gauge steel, the SC21 offers superior rigidity and corrosion resistance. I’ve also considered custom fabrication, but the cost and potential for design flaws made the Scanstrut a more appealing choice. Ultimately, I chose the Scanstrut SC21 Mast Mount for its combination of durability, compatibility, and ease of installation.

My initial impression was one of relief mixed with anticipation. Finally, a radar mount that seemed built to last! I was genuinely excited to get the SC21 installed and see how it performed under real-world conditions, hoping it would put my radar mounting woes to rest.

Real-World Testing: Putting Scanstrut SC21 Mast Mount to the Test

First Use Experience

I installed the Scanstrut SC21 Mast Mount on my 42-foot sailboat in preparation for a trip to the Bahamas. The installation process, while requiring some careful measurement and drilling, was straightforward thanks to Scanstrut’s detailed instructions. I experienced a range of conditions during the trip, from calm seas to moderate squalls with winds gusting over 30 knots.

In these conditions, the SC21 performed flawlessly, exhibiting no noticeable vibration or movement. The radar signal remained clear and consistent, even in heavy rain and choppy seas. This was a significant improvement over my previous setup, where the image would frequently flicker or distort due to mount instability.

The only minor hiccup was ensuring proper cable management, which required some creative routing to prevent chafing. This was easily solved with a few strategically placed cable ties and sealant. The robust design and stable performance gave me confidence in the system’s ability to withstand the rigors of offshore sailing.

Extended Use & Reliability

After a year of continuous use, including a full hurricane season in the Caribbean, the Scanstrut SC21 Mast Mount continues to perform admirably. There are no signs of corrosion or fatigue, even after prolonged exposure to saltwater and UV radiation. Regular washing with fresh water is the only maintenance I’ve performed, proving its excellent resistance to the harsh marine environment.

The SC21 has proven far more durable than any other radar mount I’ve used previously. Cheaper mounts tended to rust and weaken over time, requiring frequent repairs or replacements. The Scanstrut SC21 Mast Mount‘s robust aluminum construction and thoughtful design make it a worthwhile investment.
