HF, UHF & VHF Antennas
HF Antenna
The main difference between the three types of antenna is the reach. High Frequency antennas are relatively large antenna up to 9 metres long, which makes it possible for them to have a range more than 100 kilometres. This enables the possibility to communicate clearly over the said distance.gives you the possibility to communicate over a very long distance. Amongst other uses, HF antennas are suitable for Ocean going Liners to have ship to shore communication, which can be a matter of importance or just generally reporting position for an example. .
VHF Antenna
Very High Frequency antennas are not generally as large as HF antennas. However, they can transmit more data within a smaller range of kilometres. Where they lack on the distance covered they can be used to communicate from ship to ship and relays information like weather conditions or emergencies.
UHF Antenna
The last type of antenna is the Ultra High Frequency antenna, which makes it possible to send a large amount of data. It does so within a relatively short distance, as it needs more power to transmit the data. The small UHF antennas are 5 to 10 cm long and are often used for mobile devices.
