Antenna - How One Works

It's probably not something many people are interested in unless they're some kind of an electrical engineer or just bored, but insight how an antenna works can be useful when the one on your Tv or radio goes south on you and the intuit is beyond your comprehension.

Trying to clarify how an antenna works in easy English is not an easy task as there are a lot of technical specifications that need to be explained. But a normal insight is potential without getting into tech speak that would make Einstein cringe.

In order for an antenna to work it has to radiate. Your antenna, either Tv or radio has what is called free electrons running straight through it. It is these free electrons that vibrate. The interrogate becomes, how do these free electrons vibrate and what causes them to vibrate?

Well, in real life it takes an electric field to move an electron. If you take an isolated level dipole, the power comes from the combined fields of all the expensed particles, both inevitable and negative, in the antenna. We'll call this field the antenna's coulomb field.

In expanding to this field, the antenna exhibits a magnetic field that is the sum of the magnetic fields of all the free intelligent electrons. The antenna also has a dynamic electric field that is the vector sum of the dynamic electric fields of all the free electrons. What we can do is separate the electric field of the antenna at any point in space into two components. One of the components will be in phase with the total magnetic field and the other will be 90 degrees out of phase. The in-phase component is the radiation field of the antenna and the out of phase component is the induction field. At the antenna, both fields are parallel to the metal surface.

What happens is that the coulomb field and the induction field fall off much more swiftly than the radiation field as the length increases from the antenna. When you reach distances greater than a few wavelengths from the antenna, you have what is called the antenna's far field. This field is pure radiation. As you get closer to the antenna you have what is called the antenna's near field. This field is a blend of radiation, coulomb, and induction fields. Still with us? Great, we're getting to the good part.

What ultimately happens with all these fields that makes it so that your Tv or radio picks up signals straight through your antenna is this. The free electrons intelligent straight through your antenna are intelligent at their maximum speed. The right hand half of your antenna accumulates electrons. The left hand half of your antenna is where the electrons leave and leave an excess of expensed ions. The coulomb field produces an imbalance and opposes the electrons' rightward motion. The electrons then stop, coast for a bit and then head back towards the left. After they reach maximum speed they then stop and process is repeated, now heading back to the right. The ensue is a vibration of free electrons that heats the metal and in turn generates electromagnetic waves.

And that, in as easy English as possible, is how your antenna works.

VPN Router Setup With Home Network Storage - Two Essential Home Office Inventions

It is always exciting starting your business from home and equipping your home office with the tools you need to be successful. But once you have been running a business for a while, or once your business grows, you may feel that sitting in the same home office day in and day out is just a bit too, shall we say, boring? In this article you will find descriptions of two inventions that are finding their way gradually into home offices around the world. They are a VPN router, or a virtual private network router, and home network storage. Let's see how you can use both to your advantage to get you out of your house more!

VPN router, or virtual private network router usage in a home office

Yes, your home office is equipped wonderfully. You've got your desktop computer, your printer, your storage system, like an external hard drive, you have your flat screen monitors, laptops, your scanner/copier, cell phone and office phone, and more. You have connected your computers, laptops, and even phones into a home network, and a router is there to help stay connected internally and to the internet.

But now, you want more. You want the same comfort that you are accustomed to in your home office, you want that same comfort taken out with you. You want to work from any coffee house you end up visiting, you may want to work from the hotels you are staying on your trips, and yes, you have clients and you would need to connect to your home network from their office as well to grab some important documents.

A VPN router, or a virtual private network router, extends the comforts of the home network to an external, internet location. VPN router simply replaces your standard router in your home or home office. Once you connect to your VPN router from the outside of your home office, it will create a secure "tunnel" from the outside computer to your home network with all the trappings so you will feel, computing wise, as if you were sitting in your home office.

You will never again need to stay at home just to get your work done. Your city, and maybe the whole internet connected world may become your oyster.

Home network storage? Why would I need that?

"But why would I need to connect to my home network in the first place?" I hear you ask. The answer is simple. For safety of your data, you simply can not allow that all your business data be always held on your laptop computer. First, the laptop hard drives are more prone to crashes due to vibrations, and second, they are more prone to computer theft, which is much more prevalent in laptops than in desktops. So for security purposes, you always want to keep your data where it is more secure, in your home office, on your home network storage equipment. Then access that data from anywhere, either from within the home network, or from without, for instance, through a virtual private network location anywhere on the internet, connecting in through a VPN router.
