*THIS PRODUCT MUST SHIP TRUCK FREIGHT AND DOES NOT QUALIFY FOR ANY SHIPPING PROMOTIONS
The Shakespeare 476 antenna is a one-section, phased 1/2-wave collinear array, commercial VHF 10dB marine antenna. Designed to get the message through when all others fail, this unique antenna puts the signal on the horizon, providing gain in all directions. For heavy-duty seagoing applications, such as workboats, tugs, tital well service boats, etc. The reduced-length version (now 18'5") has been shortened to maintain performance while making it easier to ship both internationally and domestically.
Built for value without compromising performance or durability, the Classic Series covers the widest variety of vessels in the Shakespeare® family. These antennas keep you connected and meet essential communication needs while offshore.
