shortwave (redirected fromShort wave radio) Related to Short wave radio:Ham radio,Radio Shack short·wave (shôrt′wāv′) adj. 1.Having a wavelength of approximately 10 to 200 meters. 2.Capable of receiving or transmitting at wavelengths of approximately 10 to 200 meters:a shortwave radio. ...
More particularly, the present invention relates to a wireless FM/DMB frequency signal repeater with a wavelength adjustment function to connect various antennas of different lengths and different shapes to an antenna port by adjusting wavelengths according to lengths and types of antenna. The repeater...
Electromagnetic radiation - Radio Waves, Frequency, Wavelength: Radio waves are used for wireless transmission of sound messages, or information, for communication, as well as for maritime and aircraft navigation. The information is imposed on the electr
Fréquence Gaie came under pressure to share its FM wavelength with other newly licensed stations. Opposition to this may have provided the impetus for the station’s decision to appoint an outreach officer, Jean-Luc Romero, to raise its profile and attempt to extend its reach to other ...
1.(General Physics) the distribution of colours produced when white light is dispersed by a prism or diffraction grating. There is a continuous change in wavelength from red, the longest wavelength, to violet, the shortest. Seven colours are usually distinguished: violet, indigo, blue, green, ...
Radio waves are electromagnetic waves whose wavelength is more than the infrared rays. Therefore, the frequency of the radio waves is less than that of the infra-red rays. Wave Travel: The wavelength of a wave, {eq}\lambda {/eq} (m), is the distance...

as possible to the 1/4 wavelength of the receiving frequency. For example, to receive a 100MHz radio station, the ideal length of the antenna is L=(wave speed/frequency) /4=300000000/100000000=75cm. It is recommended to use a whip antenna dedicated to FM radio with a length of 75 cm...
The wavelength of an FM radio broadcast at a 101.3 MHz frequency would be 3 meters or 2.96 meters to be precise. And this is how. FM radio stations broadcast radio waves in the form of electromagnetic waves. Such waves travel at the speed of light and can travel through a va...
