Step 1: To begin, click on the soda Can tab. Fill the kitchen sink or toilet with soda.

Step 2: Arrange a sheet of newspaper on a table and insert the soda can. Put on work gloves.

Step 3: Using the utility knife blade, score around the soda’s top edge. When rounding the soda can, cut the front edge with scissors. Discard the beverage can’s top cut rim in the garbage.

Step 4: Fill a soda can halfway with two drops of dishwashing liquid. Fill soda cans halfway with warm water and clean them.

Step 5: Using a paper towel, wipe the soda can. In the garbage, place a paper towel.

Step 6: Insert the soda can into the newspaper. Allow it to totally dry.

Step 7: Lay the soda can on its side in the newspaper, open side facing left.

Step 8: Measure 4 inches from the closed end of the soda can. Score a hole at the 4-inch mark using a utility knife. With a scissor blade, make holes.

Step 9: Wrap duct tape around the exposed rim.

Step 10: Cut both ends of the coaxial cable with scissors. Cut a length of coaxial cable and insert it into the Coke can’s opening. Wrap duct tape around the coaxial cable to keep it contained within the location.

Step 11: Remove the 2-inch strip from the outer manning of the free end of the coaxial cable using wire strippers. Strip 1 inch of insulation from the end of the central wire using wire strippers.

Step 12: Insert the non-insulated head of the centre wire into the centre hole on the rear of the wifi plug adapter. Insert inner sheets around the conductor’s centre wire to protect it from contact. Allow a minute for the solder to cool.

Step 13: Wrap the duct tape tightly around the centre wire connecting to the wifi plug adapter to protect it from internal shading.

Step 14: Connect the wifi plug adapter to the laptop’s wifi port.

How to Build a Low Cost wifi Antenna?

Occasionally, your wifi signal does not reach the desired location. You’ve seen wifi adapters in stores; however, they’re frequently prohibitively pricey. We’ll demonstrate How to Make a Wifi Antenna for Laptop utilizing off-the-shelf components, no extra software, and without opening the cover of your computer.

1: Get a USB wireless LAN adapter “dongle”

This small device, roughly the size of a thumb, adds wireless capability to your computer. You’ll require it even if your laptop is linked wirelessly.

  • Choose one that supports both 802.11b and 802.11g standards for optimal compatibility.
  • Visit Google Commerce to find affordable products – Simple pricing, which is extremely useful at close range, costs between fifteen and twenty dollars.
  • The form is critical. To save money, choose a compact thumb-sized device. Models with a larger “squashed mouse” ($ 50-60USD) are typically more sensitive and powerful. While they can be difficult to mount, they perform better in more demanding configurations.

2: Take a dish covered with mesh

The most convenient Asian “scoop” is used for frying food in cooking equipment (such as wool-shaped, but mesh) – it is the most practical shape and includes an extended picket handle!

  • Additionally, steamers, sieves, pot lids, and lamp shades can be used — as long as they are dish-sized and metal. Any parabolic piece of metal mesh will work – this results in a stronger signal but is more difficult to transport.
  • Additional choices are abandoned direct TV pots or mesh-covered umbrellas. Although they should receive more signals, they are around 12 inches (30 cm) (300 mm) in diameter due to increased difficulty and wind resistance.
  • Desk lamps with flexible stalks enable them to be fitted and positioned conveniently.

3: Get a USB passive extension cable

You want to connect a type A (male) cable to a type A (female) cable. (They’re available in dollar stores, local computer stores, and Radio Shake.) This will connect the USB wifi adapter to the USB port on your laptop.

  • The antenna is directional to maintain its position, ensuring that it has a direct line of sight to the wifi access point. Ascertain that your job is long enough to accommodate the cable, up to a maximum of 15 feet (4.6 metres) (5 meters).
  • If necessary, numerous extension cords can be connected.
  • Dynamic USB expanders (US $10USD) extend the length of the cable, allowing for a more elevated external antenna location.

4: Target your dish

Locate the remote wifi transmitter that you wish to connect to.

  • Because your wifi antenna is quite directional, accomplishing the objective is critical. Although the remote antenna is the most effective location for levelling the dish, wandering reflections from buildings and other structures can provide correct signals from unexpected directions.
  • You can test the operation of your wireless transmitter with a low-cost hand-held laser pointer. Have a great time perusing the web with your cat!

5: Assemble the system

Use die ties, tape, or hot melt glue to secure the wifi dongle and USB extended cable to the dish.

  • You want to place the dongle at the same height as the dish’s focal point “hotspot” — radio signals enter the dish and bounce toward the centre, just above the dish’s surface.
  • A simple experiment can be used to determine the optimal location for the dongle. One approach to test this is to cover the dish with aluminium foil and observe how much light is reflected.
  • In this instance, a little support stick will be required to pry the dongle from the dish’s surface.
  • Alternative supplementary ways include tying a spider’s web of wire to the dish’s face, hollowing out plastic garden hose equipment, or even cutting sticks!

Significant Features of a Wi-Fi Antenna

802.11ac operates at a maximum of 5 GHz and employs beamforming to keep the data stream more direct to the client devices. Older wifi antennae and cards may default to 802.11n, which may not provide the fastest data transfer rate.

USB Type – Unless your computer is more than a decade old, you should have USB 3.0 ports. It is capable of speeds of up to 5 gigabits per second (or about 640 MB per second). If you’re limited to USB 2.0, you’re looking at a maximum data transfer rate of 480 megabits per second (or 60 MB per second for data transfer).

DBI Antennas – Antennas are classified as DBi, often for the 2dBi or 5dBi that we are interested in. 5dBi antennas are more effective at picking up weak signals (from a greater distance) than 2dBi antennas. However, 2DBI can retain high correlations in the presence of powerful signals.

Advantages of Laptop Antenna

There are instances when a laptop wifi antenna booster is quite beneficial. The first is when I’m staying in a hotel, guest house, or hostel and the wifi connection isn’t strong enough to reach my room.

There may be a single router, and it may be located in a public space. By attaching my external wifi antenna, I am able to work from the comfort of my own room with strong signals.

This range is around a few hundred yards, depending on the number of walls/buildings.

The second circumstance occurs when I locate the ideal cafe for working (atmosphere, coffee, prices, food, and comfort), but their internet connection is unavailable. A restaurant down the street, on the other hand, may have a far better relationship.

I can connect to another cafe’s fast internet using my wifi antenna while working from the restaurant, which is what I prefer.

It may not sound like much, but being a digital nomad on the road, I need to find a large workplace with strong internet to maximise my productivity.

FAQS – How to Make a Wifi Antenna for Laptop

How do laptop wifi antennas work?

Slots (for CDs), holes (for keys, screens, and wires), and seams are a few examples. Indeed, the antenna’s electric field is blocked from entering the casing. Due to the fact that charge carriers (electrons) in metal seek the lowest possible electrical potential, this electric field induces RF currents in the case.

How can I make my wifi antenna stronger?

Consider moving your router and other equipment to the 5GHz frequency band, which features a large number of channels. If your router does not support 5GHz, change the device’s track selection. Microwave ovens operate at the 2.4GHz frequency spectrum as well.

Do wifi antennas really work?

Is the antenna a receive or a send device? They are both. Although a wifi signal contains data given and received by both parties, it is critical to understand that the antenna enhances the likelihood of the radio attached to it succeeding.

Do antennas help wifi?

Almost often, WiFi vendors slap on inexpensive antennae. However, you can purchase an expanded antenna, which often provides increased range and performance. By replacing the antenna(s) on your router, you can improve overall coverage.
