What is line of sight (LOS) and why is it important?

WebFrequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). VHF radio waves propagate mainly by line-of-sight, so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond the visual horizon out to about 160 km (100 miles). WebLine-of-Sight (LoS) propagation is a characteristic of electromagnetic radiation in which two stations can only transmit and receive data signals when they’re in direct view of each other with no obstacles in between. Satellite and microwave transmission are two common examples of LoS communication. All radio waves with a frequency greater ...
