When it comes to antennas, it is necessary that we start by alerting the people that they are always found in three categories. These categories are communication, navigation and entertainment. In the communication category, we have satellite, VHF, cellular and satellite. The type of vessel matters a lot when one is buying a VHF antenna. It is needful for individuals to understand that small antennas will be needed in small vessels and the vice versa is true. Regardless of the kind of boat that you have, it is always necessary to know that the key concerns should be the mounting height, gain and Standing Wave Ratio. An antenna will be differentiated from another through the effectiveness if the radiating power, it should be known by the people that marine antennas tend to have a higher gain which means that its range is a longer one. To select the most suitable gain, you should always check on the type of vessel as the increase in gain will depend on the width of the transmission.
When buying a VHF antenna, it is necessary that you focus on the Standing Wave Ratio. This is what will rate the amount of transmission signal that reaches the destination. Standing Wave ratio is the measure of the efficiency of the antenna. If the energy fails to reach the final destination, you need to be aware that the signals of the transmission as well as that of reception will be poor. It will also be necessary if you check on the shape of the transmission. Every DB rating will have a different shape, and this is a fact that should be known by the people. While some will have a round shape, it is needful to say that others will be more elongated. Beams will always leave the antenna in different directions, and this is known by a few people. The right antenna to choose is that whose angle of radiation is low. If the angle of radiation is low, then it means that the signal of travel will be closer. If you are a buyer, you should also consider the price of antennae before purchasing. Check with a number of suppliers so that you can get that who will be willing to sell the antennae at a good rate that you will afford.
The qualification of VHF is that of technology that is on the line of sight. This means that the choice, as well as the placement of your antennae, will be the factors that will enable you to have the actual transmission range increased. The interference with VHF will be done by almost all the things that aboard a boat. These may include the engines, Depth sounders, TV screens, radios, cellular telephones and other. You, therefore, need to check on a few things before you mount the antenna. The antennae, as well as the cable, should be kept away from lights that are fluorescent. If you are using the cable extensions, it is necessary that you consider those that are of quality. If you consult a marine electronic dealer, he will assist you in getting a suitable antenna that will be best for you.
