Scanstrut SC111 PowerTower® Starboard Mounted Bar f/GPS/VHF/Navtex Antenna

The Scanstrut SC111 PowerTower® Starboard Mounted Bar for GPS, VHF, and Navtex antenna installation is purpose-built for marine electronics integration on vessels requiring multi-frequency communication and navigation capabilities. This starboard-mounted antenna tower addresses a critical need for boaters and commercial mariners who demand reliable signal reception across GPS, VHF marine band, and Navtex emergency weather channels without compromising deck space or vessel aesthetics. The SC111 consolidates three separate antenna functions into a single, engineered mounting solution, eliminating the clutter of individual mast attachments while maintaining optimal vertical separation and signal isolation.

Scanstrut engineered the PowerTower® design using rigid structural geometry that isolates antenna elements vertically, preventing frequency interference and cross-talk that degrades marine radio clarity and GPS accuracy. The starboard mounting configuration distributes weight (2.5 lbs) evenly along the vessel's side rail, reducing center-of-gravity impact while offering unobstructed antenna radiation patterns in all directions. Compact at 13 by 1 by 19 inches, the SC111 mounts securely without protruding excessively, making it compatible with railings, hardtop frames, and cabin-top installations on recreational and professional vessels ranging from 25 to 65 feet. The powder-coated finish resists saltwater corrosion and UV degradation, critical for maintaining signal integrity in extended offshore duty.

Captains, fleet operators, and marine technicians benefit from the SC111's modular antenna support, which accommodates standard GPS, VHF, and Navtex whip or vertical monopole antennas without requiring custom fabrication or heavy structural reinforcement. Installation requires basic fastening to existing rail systems or bulkhead mounts; most marine electricians complete setup in under two hours. The SC111 delivers particular value for coastal cruisers, charter vessels, and commercial fishing operations where redundant communication systems and real-time weather data integration are regulatory requirements or operational necessities.
