Extra Heavy-Duty Antenna Mount
Complete Your Purchase
Style 4187-HD is an extra-heavy-duty stainless steel ratchet mount designed for use on high-speed boats, featuring large antennas and operating in harsh conditions.
This versatile four-way ratchet mount provides a durable solution for deck or side installation on both slanted and level surfaces, crafted from extra-heavy-duty stainless steel for maximum strength and rigidity. The quick-action handle allows smooth raising and lowering of your antenna, while the ratchet ensures it returns precisely to its upright position, making it ideal for high-speed boating or high-stress setups such as hardtops, T-tops, and radar arches. Designed for convenience, it features 5/16-inch bolt holes spaced 3 inches by 1-1/2 inches on center, a special 9/32-inch cable feed-through hole to avoid removing most factory connectors, and a standard 1-inch 14-thread male mount. With a base diameter of 4-1/8 by 2-1/4 inches, this mount delivers the same reliability as Style 4187 but with added strength, making it the go-to choice wherever extra heavy-duty performance is required.
