Shakespeare 4351 3' AM/FM Boat Antenna with 1"-14 Thread

The Shakespeare 4351 is a one-piece AM/FM boat antenna measuring 3 feet in height, built for boaters who want to keep listening to their favorite AM and FM stations while out on the water. It is designed as a classic combination AM/FM antenna with brass and copper elements that provide standard range and reception across a frequency range of 550-1600 KHz (AM) and 88-108 MHz (FM). The antenna body has a smooth, durable, high-gloss white fiberglass finish engineered to resist yellowing over time, so it keeps a clean look season after season.

Mounting is handled through a nylon ferrule with a 1"-14 thread, which is compatible with standard marine antenna mounts (mounts are sold separately; Shakespeare recommends its 4187 or 4186 mounts). The antenna comes with 10 feet of RG-62 coaxial cable terminated in a Motorola plug, ready to connect to your AM/FM radio. It does not require an external grounding system and performs equally well on fiberglass, wood, or metal boats. Installation is straightforward: pick a mounting location as free as possible from obstructions and other antennas or RF sources, secure the antenna in a compatible mount, and route the included cable to the radio.

The Shakespeare 4351 is backed by a 2 year warranty, making it a dependable, no-frills choice for boaters who want reliable onboard AM/FM reception without a complex install.
