Do you know the difference between omnidirectional verses directional antennas and which you should be using for your situation? The right choice for your application can make the difference between great system performance and just marginal results.
The main difference between the two types is in their acceptance/radiation pattern or how they emit and receive signals. RF loss, also known as signal loss or attenuation, is the reduction of signal strength that occurs as a signal travels. RF loss can be caused by a variety of factors, including absorption, reflection, scattering, diffraction, and refraction, as well as the frequency of the signal. When an RF signal is transmitted, it loses power as it travels. Signals with higher frequencies tend to experience more RF loss than signals with lower frequencies. Getting into specifics as to the differences:
