What are External Antennas for Wifi?
Introduction to Wi-Fi Wireless Antennas
Wi-Fi wireless networking is basically the same thing as normal radio. Radio waves, or frequencies are broadcasted from an antenna to another receiver antenna. This is basically what a wireless modem is, the radio station’s antenna. This same principle works whether it is wifi on your PC, laptop or mobile phone.
There is a way to broadcast and to receive.
But sometimes the signal isn’t strong enough to get. Like when you get a weak signal or you can’t connect your laptop to your internet while you were upstairs in your bedroom because the signal wasn’t strong enough, then that’s why you need an external antenna.
All the “external” part means is that it isn’t “inside” your PC or laptop. It is an outside connected device.
These devices can usually work with any kind of modem to help boost and send your signal further. There are all kinds, but the onidirectional antenna is the most common for home use. This is because it can boost your signal to anywhere you are, they just can’t send the signal as far as many of the more expensive units like the Yagi Plug and Play directional WiFi Antenna can.
Although these types of antennas may not be as strong, they can really help you in smaller spaces like your home or a small business office.
The Telstra external antenna for wireless broadband can hook up to any type of modem, even wirelessly. But you need to be careful when using a cable as the ends may not match up. So be sure you’re using the right cable end sizes. These are different according to the model you purchase, so you’ll need to do a little digging.
Another thing you need to be careful of is the amount of GHz the system is running on. It’s a bit like a 110V and 220V electricity in your homw. Using the worng equipment with the worng signals will simply not work. All units are clearly stated which GHz they are using.
Get a bigger antenna; your WiFi will go a lot further. When you need something for outdoors or you’re trying to receive a signal from a long distance, say like a mile, then you’ll need something bigger. The small home antennas that you set up next to your modem just aren’t going to cut it. But with the correct set up like a Yagi Antenna, you can sometimes send signals for miles.
Also, when you’re going long distances you’re probably much better of with a directional antenna rather than omnidirectional. That’s because the more focused the signal, the farther it can travel. Think laser beam.
The distance you can receive a signal also has a lot to do with what’s between you and the signal. Is there a dense forest, concrete? How’s the weather? Rain and lightning effect the signal strength a lot as well.
These are getting more common as the technology catches up. People are placing them on their RVs and even cars. The idea here is you’re able to travel while still receiving a signal. The signal is captured from smaller towers that are in your area.
There’s a bit to learn when it comes to antennas. But you do need to understand the basics if you’re going to make a wise buying decision. And if you have any questions, just comment below and I’ll do my best to answer.
