Frequently Asked Questions
What is the primary advantage of a 3dB gain antenna?
A 3dB gain antenna provides a balanced performance, offering adequate signal strength for communication without requiring a very long antenna length. This makes it suitable for vessels where mounting space is a consideration.
Can I use this antenna for AIS or DSC transmissions?
Yes, this antenna is suitable for use with AIS (Automatic Identification System) and DSC (Digital Selective Calling) devices, provided they are connected to a VHF radio that supports these functions and the antenna is properly installed.
What is the recommended VSWR for this antenna?
The specified VSWR (Voltage Standing Wave Ratio) for this antenna is 1.5:1 at 144 MHz, indicating efficient power transfer and minimal signal reflection for optimal performance.
Does this antenna come with a mounting bracket?
This antenna features a standard 1"-14 thread, allowing it to be mounted on a wide variety of standard marine antenna mounts. A separate mount is typically required and sold independently.
How do I know if my VHF radio is compatible?
Your VHF radio must have a PL-259 coaxial connector to attach to this antenna. Most marine VHF radios manufactured in the last 30 years utilize this standard connector.
