Questions & Answers
Is this a genuine Shakespeare part?
Yes, these are original Shakespeare 427-S antennas. Shakespeare is a global leader in marine communications, known for durability and signal clarity.
How do I know if it is compatible with my mount?
The 427-S uses the industry-standard 1" x 14 TPI (threads per inch) stainless steel ferrule. This fits virtually all standard marine ratchet, rail, and deck mounts.
Why choose a 3dB gain antenna over a 6dB one?
A 3dB gain antenna has a wider vertical radiation pattern. This makes it more effective on smaller vessels that roll and pitch in the waves, as the signal is less likely to be "thrown" into the sky or water compared to a high-gain, narrow-beam 6dB or 9dB antenna.
Note: Each pack contains two (2) 1.5m antennas. Please verify mounting space and cable routing requirements before installation. Visit 4boats.co.uk for more marine equipment.
