Hence the received power will be unchanged. Newsletter to keep you inspired with new projects and more product reviews. Yoghurt instead of yogurt? Just like wiif but the Comcast router also is active on WiFi. And this is why dB is an insane system of units.

How To: Make a simple WiFi Yagi antenna

Normal 9dBi yagi antennas have a lot more elements to reach that number — the driven element, the reflector, and at least three directors. Who ever thought that was a good idea? Fill in your details below or click an icon to log in: Buy the router as above.


I quote my words above: Maybe some empirical testing would be worth mentioning. This one only has one director. The simulation predicts 8. When we take huild new Wi-Fi router from its box, the stock antenna is a short plastic stub with a reverse SMA plug on one end.

With more antenna gain, the power needs to be reduced.

You are commenting using your WordPress. While it is a half-duplex technology, there are no receivers and transmitters. A number of very much type-approved directional antennas frequently used in commercial WiFi in the USA disagree with your statement as it is written….

Be aware that, to remain legal, if you use a 10dB antenna then you must reduce the transmit power by 10dB. The transmit power is unchanged, only the EIRP increases in the main direction.

These antennas do a reasonable job of covering a typical home, because a vertical sleeve dipole is omnidirectional. Give it a try, and bring connectivity back to far-flung corners of your home!
