Ferrite beads have been used for a long time as a medium for radio and microwave transmissions. The frequency range and power levels they can handle are quite high, so you do need to be careful when you are choosing one. You also have to remember that these types of materials are extremely dense, so they are not easy to use in other applications like in a fountain. Here are some important tips to help you find the best ferrite bead filter for your home.
A first thing you will want to look at when you are looking for ferrite bead filter is what you are going to be using it for. For example, you may be interested in one for a home security system, or for monitoring a radio or microwave transmission. In this case you are not going to want to choose a material with a higher bandwidth to cover the area you want to cover. Rather you are going to need to choose something with a lower bandwidth but one that has enough power to cover your needs.
The next thing you want to consider when buying a ferrite bead filter is how much power you will be using on your transmitter. This will determine what size of antenna you should get as well.
Some transmitters require a wire harness. Some transmitters may use a dipole antenna while others use an inverted-dipole antenna. In either case, you will need to purchase a ferrite bead filter with the proper power requirements. These filters will work best if they are purchased along with the appropriate transmitter so you don't end up buying two filters that won't fit.
Ferrite beads are very dense, so they do not easily pass through objects that are more than a couple millimeters thick. If you are planning on mounting a transmitter where the thickness exceeds a few millimeters then you may want to look for a ferrite bead filter that has a thicker diameter. While this may cost more initially, you will end up saving money in the long run by having a filter that works better.
One of the best ways to learn about new ferrite bead filters is to search online. There are several companies that will let you try them out before you buy. There are also sites that will let you buy online and have the opportunity to compare the prices, features, and customer reviews for each manufacturer.
