If you are interested in boosting the range of your current WiFi, you can opt for this DIY tin can antenna (cantenna) for the cheap (under $5).
It is pretty simple to make.
Below are some frequently asked questions about DIY WiFi Antenna;
What is a Cantenna WiFi?
A cantenna is a directional waveguide antenna for long-range WiFi (cf. Hi-fi) which can be used to increase the range (or snoop) on a wireless network. Its design is so simple and ubiquitous that it is often the first antenna that WiFi experimenters learn to build.
What are the items needed for making a cantenna?
The things you are going to need for this DIY home project include:
- A tin can (minimum diameter of 3 inches)
- An N-type female jack panel mount connector.
- About 1¼” of 12-gauge copper wire.
- Four nuts and bolts.
- Permanent marker.
- Soldering iron.
- Internet modem.
How does a Cantenna work?
The aluminum can act as a medium for the radio waves to be guided through, hence the term waveguide cantenna. Radio waves will be “guided” into the can and interact with the wire element, which sends a signal down the pigtail cable and then to your computer or router.
Can you get Internet for free?
All Free ISP is a website that stores a database of free internet access service providers. You will need to enter your state/province and your local area code. This will then bring up all of the free (and cheap) internet providers in your area. They also provide ratings for each free ISP so that you can compare them.
Why does touching an antenna improve reception?
Again, if the impedance change makes more energy transfer into the TV, the signal will get better. If the touch makes the antenna more resonant at the desired frequency or if it changes the pattern such that it has more gain in the desired direction, then the reception will improve.
How can I get Internet without cable or phone line?
Fixed wireless internet
Certain internet providers, such as AT&T, offer fixed wireless home internet that you can get without a phone, cable, or a fiber line. Fixed wireless internet is particularly helpful if it’s available in a rural area where you don’t want to buy satellite service.
Do longer WiFi antennas work?
A longer antenna has the advantage in that it has a larger area to pick up the signal from the client devices. This resulted in higher uplink speeds as well as fewer dropped connections on the 2.4GHz band.
Can I put a bigger antenna on my wireless router?
Replacing the antenna(s) on your router can give you better overall coverage. Replacing the antenna(s) on the wireless adapter will give you a better range for that particular computer. Keep in mind when shopping, the higher the gain (measured in dBi), generally means the further it will transmit and receive.
How far can a WiFi antenna reach?
This wireless router emits a signal that a WiFi detector is tuned to pick up. A wireless signal can travel only so far. Specifically, a typical signal can extend as far as 1,000 feet (304.8 meters) in an unobstructed, open area and about 300 feet (91.44 meters) in a closed area that has obstructions.
Do trees affect the antenna signal?
Large trees can interfere with antenna reception. Tall structures such as trees interfere with the signal by obstructing the signal waves or reflecting them off their foliage.
