RF is the acronym for radiofrequency. It's also a frequency that's within an electromagnetic spectrum. Adding to that, it's associated with the propagation of radio waves. The RF current is usually supplied to antennas. When that happens, an electromagnetic field will be produced which will then propagates through space. As you may already know, most wireless techs that we have today rely on the propagation of radiofrequency. Of course, the frequencies are what make up the spectrum of the electromagnetic radiation.
One thing that you should know about electromagnetic radiation is that it is made of electrical waves and magnetic energy. They also move through space at light speed. To make things short, it's general to assume that all electromagnetic energy and all types of it are what we call the electromagnetic spectrum. Most of the time, the transmission antennas are the ones that send and receive radio waves most of the time. Basically, having an electromagnetic field or radiofrequency is essential when it comes to detecting RF energy and other electromagnetic frequencies.

When it comes to the RF field, you should know that it has both a magnetic and electric component or a magnetic and electric field. There are also ways to measure the intensity of radio frequencies in certain areas. Of course, that would depend on the electric and magnetic fields that are present at a certain location. Also, you should know that the 'volts per meter' is the unit that is used when it comes to determining the strength of an electric field. As for the magnetic field, you'll have to use the 'amperes per meter' computation. Be sure to click here for more info!
If you want to know more about RF waves, you have to realize that they're characterized by a frequency and wavelength. To visualize, the wavelength that covers a certain distance through a complete cycle is what you call the electromagnetic wave. As for the frequency, it's about the electromagnetic waves converging to a certain point where unit of time is also used for the computation. As you may already know, hertz or Hz is the term that represents RF signal frequencies. One hertz is basically a one-second cycle. Just like in most measurements, one megahertz is equivalent to one million cycles each second. In any case, you should know that RF waves can be categorized by different forms. The frequency and wavelength are used in order to do that. Be sure to read more now!
