When it comes to marine communication, the VHF antenna is by far the most important component. In order to ensure reliable and clear radio communication between vessels, it is essential to select the right marine VHF antenna for your vessel.
Determine the Antenna Type
There are three main types of marine VHF antennas – whip antennas, antenna masts, and fiberglass antennas. The whip antenna is the most basic and economical option, and is suitable for smaller boats. The antenna mast is more robust and provides better performance, but requires a larger mounting area. Lastly, the fiberglass antenna, such Retevis MA06, offers the highest gain and durability, and it is suitable for bigger yacht.
Choose the Antenna Length
Generally, the longer the antenna, the better the signal range. However, it is significant to consider the size of your boat and the surrounding environment when selecting the length of your antenna. A longer antenna may be necessary if your vessel is in an area with a lot of interference.
Consider the Antenna’s Gain
In addition to the length, you must also consider the antenna’s gain. A higher gain antenna is more efficient, resulting in better performance and a longer range. However, keep in mind that a higher gain antenna will also require more power to operate.
Find the Best Mounting Option
If possible, it is best to mount the antenna as high as possible, as this will result in better signal reception. However, if your vessel does not have a suitable mounting area, you may need to use a mounting bracket or rail.
The Recommend Marine VHF Antenna
Retevis MA06 is a marine VHF antenna with SL16J Connector which is compatible with Retevis RA27 and Retevis RM20 marine VHF radio. This antenna is designed to enhance your VHF communication range. It offers superior performance in the VHF band with a maximum gain of 3.5dBi. This marine antenna is also IP66 rated, meaning it is protected against splashing, falling, or dripping water. Using pure copper vibrator and high-quality copper cable components, MA06 provides good coverage and efficiency of transmission. And the antenna’s angle can be adjusted to 180°. This marine antenna can be used in many situations, such as motorboats, yachts, small and medium motorboats, trucks, recreational vehicles, cruise ships, kayaks, and outdoor activities.
