Heinrich Hertz proved the existence of radio waves in the late … WebbA resonant quarter wavelength with a dedicated counterpoise or earth system results in a feeding point impedance between 35 and (say) 60 Ohm pure resistive. That is an …

WebbIn telecommunication, the free-space path loss (FSPL) (also known as Free Space Loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air). The "Standard Definitions of Terms for … WebbBlueComm 200 UV works just like BlueComm 200, however it uses a shorter wavelength in the ultra-violet spectrum. This means that it can operate even in the presence of artificial lights. Operating in the UV spectrum, BlueComm …
