WebDec 19, 2016 · The primary mode of propagation for VHF radio waves is through direct waves. These travel in a straight line, becoming weaker as distance increases. Transmitting and receiving antennas must be able to ‘see’ each other for communications to be effective, so antenna height is critical in determining range. WebRadio waves are a type of electromagnetic radiation. A radio wave has a much longer wavelength than visible light. Humans use radio waves extensively for communications. …
