Mar 24, 2008 - The first antenna we'll look at is called a Cantenna. 802.11n can use both 2.4GHz and 5 GHz, but you can get away with only the 2.4GHz signal - it. For an online calculator or you can run through the equations yourself.
5.5 GHz cantenna as a feed horn
Acantenna(a portmanteau blending the words and phrasescanandantenna) is usually a homemade directional waveguideantenna, made out of an open-ended metallic can.
Cantennas are typically utilized to boost the variety (or breakthrough discovery) of Wi fi networks.

A Pringles cantenna for Wi-Fi
The canister portion of the may may consist of metal-coated paperboard.
Although some styles are based on a Pringles spud potato chips can, this pipe is as well slim to raise the 2.4 GHz indication by a useful quantity, although at 5 GHz it would become about the correct dimension.1However, a cantenna can become produced from numerous cans or tubes of an suitable diameter.2Some designs consist of a post mount to elevate the cantenna.3
At 2.4 GHz, loss can occur if the cable from the cantenna to the Wi-Fi circuitry can be too lengthy. A even more effective cantenna can end up being produced by minimising this length or linking the cantenna straight to the Wi fi circuitry.4

Cantennas are usually typically utilized for increasing a cellular local area network (WLAN).
The small design makes them ideal for mobile applications such as wardriving.
Cantennas can be used to increase cell cell phone variety,5improve reception, and decrease sound.
A cantenna can be used as a satellite television dishfeed horn. The 5.5 GHz cantenna sizes are almost perfect in that they create a good fit for the standard TV satellite television dish. The causing setup can be a cheap high-quality high-gain antenna.6Like setups are usually widely utilized in cellular community networks for long-distanceWi-Filinks.
Cantennas may be utilized with additional RF devices like as wireless security video cameras.7
Cantennas can furthermore be utilized for SETI with small modifications: in this case the cover is left in place so drinking water can't get in and a little pin drilled so any moisture may deplete out.This can be utilized with an present satellite Television meal if it is definitely in a good problem.

Aim at resource and adapt to obtain the best signal.This should become much stronger than the mix antenna you acquired just before. To enhance the sign even even more - much more - reduce a 2 foot (0.6 michael) wide by 1 foot (0.3 meters) high linen of tangible lathing display with1⁄4in . (0.6 cm) or smaller sized openings and curve it somewhat to form a parabolic meal, identical to a Television satellite dish. Instead of directing the may at the transmission source, point it at your screen which points at the transmission so the back of the can points at the sign. It requires a little bit of changing to obtain the shape of the display screen and distance to the can exactly best. You can discover formulations for determining the precise focal stage or make use of test and error since you will see your indication gain dual or even triple when you obtain the contour and range just best. You can after that create a wooden or aluminium frame to hold everything together in the right placement. You can also use a true satellite meal and spot the cantenna at the finish of the limb at the place the Television antennas (the horn) generally move.
