In EU the limits of use for 2. I think that is his point. Stupid question from a non-radio guy: The rule is your EIRP cannot go over a certain amount. I looked it up: So, what can I eassy to increase my range? Much tastier than yogurt, which is clearly inferior. OTOH, you can use a high gain antenna on the receiver without restriction; this reduces the interference you suffer due to other ajtenna. I have been playing around with some wifi networking lately, mostly with the La Fonera, and finally decided to build a directional wifi antenna.


Thanks for your submission.

A number of very much type-approved directional antennas frequently used in commercial WiFi in the USA disagree with your yati as it is written…. By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies.

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

Because it would take many times longer to print than to measure out and cut, never mind the design time. 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.


The key point is that the transmit power is defined as EIRP effective isotropic radiated poweri. You will also be receiving the weekly Make: While it is a half-duplex technology, there are no receivers and transmitters. All cards are both transmitter and receiver, so you could not only use a receiver antenna. The simulation predicts 8.

In other words, the receiver uses whichever antenna receives the strongest signal. 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.

I am hugely skeptical of 8. Give it a try, and bring connectivity back to far-flung corners of your home! Unless your transmit power I already below the FCC limit.

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.

In the US that would mean: You are commenting using your Twitter account. At least try to put them on separate channels or something.
