Why is the Height of a VHF Radio Antenna Important?

When you're out at sea, VHF radio is often the only means of communication between you and others. Since it is such an important piece of communication equipment on board, there are a few things every boat owner should know about this vital piece of equipment.

Due to the line-of-sight requirements of the radio, a clear path is required between the transmitting point and the receiving point. Various placement conditions must be considered to ensure this clear path. Therefore, the VH antenna height is important for two antennas to communicate within line of sight of each other.

 

 

Besides the height of the antenna, its location is also important. Placing the VHF antenna at a higher altitude increases the range of radio coverage. A higher placement point will also allow our transmitted signal to clear most obstructions such as trees and other boats.

 

 

Let's imagine two people. For these people to talk to each other, they need to see each other, and without visual confirmation, communication fails. This is exactly how a VHF antenna works; the transmission of the VHF signal depends on this established line of sight.

 

 

Important boating equipment like a radio deserves proper attention. Hopefully we can provide you with more insights into important information about your primary communication devices. Feel free to leave your comments as we’d like to hear from you.
