Wave Travel: The wavelength of a wave, {eq}\lambda {/eq} (m), is the distance the wave travels in one cycle. The period of a wave, {eq}T {/eq} (s), is the time for one cycle of the wave to pass a given point. If the speed at which ...
Best range is achieved with either a straight piece Figure 4: QFMT5 Transmitter Application of wire, rod or PCB track @ ¼ wavelength Circuit (15.5cm @ 433.92MHz). Further range may be achieved if the ¼ wave antenna is placed ANTENNA perpendicular in the middle of a solid earth plane...
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...
The VHF or very high frequency band within the overall ITU designations for the radio spectrum falls between 30 and 300 MHz, and has a wavelength between 10 and 1 metre wavelength.The bands are not as affected by the ionosphere, although at times the lower frequencies are. Th...
More than 20 years later, FM radio was born, and FM stereo broadcasting didnt appear until 1962.What is wave?Velocity = wavelengthelectromagnetic waveMW: 10 kHz in China9 kHz in the United StatesShort wave: 10 kHz (digital radio tuned b 8、y 5 kHz) FM: 200 kHz (digital radio tuned ...

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 ...
