Text and links: If this is your first time using a VHF antenna at your home or out on a boat, it’s a good idea to practice with it. With boats, the antenna is normally factored in to the cost to buy a yacht, but can always be added later on. A good VHF antenna is an important safety feature for ships, but remember to ground it in case of lightning.
