Diy wifi cantenna

If the reflection is high compared with the foward wave there is a bad match, poor performance will result and the dimensions of the antenna would need altering. Reply 8 years ago on Introduction. If impedance of the antenna is too high or too low, the transmitter router will see the antenna as ah dead short resulting in high SWR that can burn up the final amp in the router transmitter. So impedance matching is Very important. I want to try this out but the cantenna calculator is lost???

The link doesnt open the calculator. Sorta like the pringles cans I have seen around. I wonder if having a smooth interior or the ribbed kind affect the signal in any way. Also, I don't use the coax connector for my wifi. I have a USB adapter So i would have to adjust this somehow. Reply 10 years ago on Introduction. Reply 11 years ago on Introduction. Dude, this one is so easy to do. I wrapped a 1" band of aluminum around with 3" of handle below.

I have built every one of these Wifi antennas. Sounds really good How about an instructable????! Go here: www. Luch, Mr Steve. Even a novice can boost a wireless signal using these four methods to make your own WiFi signal booster. However, if you want better results buying a wifi extender will be better.

Using a DIY WiFi booster is an excellent way to improve your signal for little to no investment, other than a few minutes of your time. Several things can impact the WiFi signal, from the thickness of walls to the usage of microwaves near the router. Creating your own WiFi signal booster to get around this problem can be achieved in many ways. The easiest of all the signal boosting methods shown here, with highly effective results, uses aluminum foil to create a DIY Parabolic reflector.

Mark this location with a Sharpie marker Note : This will be the location of the copper wire element. Drill or cut a hole into the can making sure that the center of the circle lines up with the measurement above.

Drill four screw holes into the can using the N-connector as a guide for their location. Note : This part is tricky because it needs be 31 mm from the point it exits out of the N-connector. In order to solder it into the connector, it needs to be a bit longer. I suggest cutting a larger piece, fitting it into the connector, and then trimming it down after it is installed. Once you have the copper element cut to size, it needs to be soldered into the connector.

If you have never soldered before, learn how , and then cut a few pieces to practice with before working on the actual connector. Caution : Be careful not to melt the plastic contained in the N-connector. It melts easy, so I would suggest using a soldering iron that has lower heat and a fine-tip.

Your cantenna is almost done; just connect the pigtail cable from the cantenna into a wireless router or wireless USB dongle. The router or dongle needs to have a removable antenna.

The picture below shows the classic WRT54G being used. The great thing about this router is that you can add DD-WRT firmware , which will give you the ability to choose which antenna is transmit and which is receive. It will also allow you to adjust the power so you can increase the range even more. 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.

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. Replacing the antenna s on your router can give you better overall coverage.
