A Simple Yagi Antenna For Your Wi-Fi Router | Hackaday

Notify me of new comments via email. Stupid question from a non-radio guy: All cards are both transmitter and receiver, so you could not only use a receiver antenna. Much tastier than yogurt, which is clearly inferior. I boosted a wireless router in bridge mode by placing it in the bottom of a mesh steel wastebasket propped up on a chair and pointing out the window. At least try to put them on separate channels or something.

For those concerned about EIRP, know that the guy who did this is an amateur radio operator and is therefor legally able to run higher power levels effective or actual than unlicensed individuals as long as the transmissions meet all applicable laws.

Get the Magazine Make: The simulation predicts 8. The reason is that the power limits are defined to contain the chance of interfering with other users.

Fill in your details below or click an icon to log in: That would also require following all the other ham radio rules. Do we need to be careful not to be antisocial with this kind of modification?

As you move your phone or laptop, etc. Welcome to the Make: Because it would take many times longer to print than to measure out and cut, never mind the design time.

How To: Make a simple WiFi Yagi antenna | Make:

I am hugely skeptical of 8. Go into the setup of the Comcast router and turn the wireless 2.4guz off. Newsletter Stay inspired, keep making.

There is no transmitter and receiver in wifi. I did something similar once, when our office internet was out and I knew someone in the building across the street. Please check your email. I have been playing around with some wifi networking lately, mostly with the La Fonera, and finally decided to build a directional wifi antenna.

But if you are planning to keep the same coverage in other directions when using this mod, you will find out where that extra signal came from. Sign up for the Make: Bulld do you use this with a two-antenna presumably dipole router? If you use a high gain antenna on either end, it will not only boost the received signal, but the transmitted one aswell.


Be antemna that, to remain legal, if you use a 10dB antenna then you must reduce the transmit power by 10dB. More recent and more fancy routers have more than one such antenna for clever tricks to extend their range or bandwidth, but even if the manufacturer has encased it in mean-looking plastic the antenna inside is the same.

There is overlap for To assume that you cannot to any degree focus the energy in one direction more than the stock antenna already did is to assume that the EIRP of the router with the stock antenna was already sitting right at maximum.

Configure the Comcast router to have the ip address of your router as a DMZ. Your changes have been saved.

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.
