Those first two though. Normal 9dBi yagi antennas have a lot more elements to reach that number — the driven element, the reflector, and at least three yaig. For those concerned about EIRP, know that the yag who did this is an amateur radio operator and is therefor buuld able to run higher power levels effective or actual than unlicensed individuals as long as the transmissions meet all applicable laws.

Are you referencing the rules of some other country? The key point is that the transmit power is defined as EIRP effective isotropic radiated poweri. Some examples of correct use: Get a high gain antenna like a 15 element yagi. This one only has one director. Sign up for the Make: Assuming the antennae simply contain a pair of dipoles can anyone provide a link to a teardown of the typical dual-band antennae that come with consumer routers? Or will the 2.

A Simple Yagi Antenna For Your Wi-Fi Router

Who ever thought that was a good idea? Nick sent yaig this great build for improving your WiFi connection. Find the wlan adaptor with the highest receive sensitivity dBm dBm. Much tastier than yogurt, which is clearly inferior. How ever, I have a cable set-up Xfinity supplied by the company; and the router does not have an antenna that I can see. Thanks for your submission. WiFi emissions rules vary by country. Interesting misspelling at least. Go into the setup of the Comcast router and turn the wireless part off.

But best to use it so that it directs the power onto your own premises — You do normally not want to supply your neighbor with your wifi connection: Stupid question from a non-radio guy: Antnna, you can use a high gain antenna on the receiver without restriction; this reduces the interference you suffer due to other transmitters. Hence the received power will be unchanged. All cards are both transmitter and receiver, so you could not only use a receiver antenna. In the US that would mean: This site uses Akismet to reduce spam.

I looked it up: How do you use this with a two-antenna presumably dipole router?

Education How making is transforming learning. Email required Address never made public. You are commenting using your Twitter account. I could be very wrong though.

At least try to put them on separate channels or something. Give it a try, and bring connectivity back to far-flung corners of your home! Buy the router yourself as seen above. Notify me of new posts via email.

I am hugely skeptical of 8. If I wanted to find Wifi transmitters on a certain frequency, what kind of antenna would I use? With more antenna gain, the power needs to be reduced. That statement is misleading at best, as an ideal Yagi 2.4gnz yields 7.

I have been playing around with some wifi networking lately, mostly with the La Fonera, and finally decided to build a directional wifi antenna. Newsletter Stay inspired, keep making. Good to see someone actually simulate and design a directional antenna modification rather than balancing pieces of tin foil and drawing circles around the router with salt.

I think you missed the point that Wireless LAN is not unidirectional. Why is no one 3D printing these already?!

Yoghurt instead of yogurt? It needs to be compared to something so we get an absolute value. By Marc de Vinck Marc de Vinck. I think that is his point. Welcome to the Make:
