How to Improve Your Wi-Fi Signal

Wi-fi tip - perpendicular placement for antennas

If you have a router with adjustable antennas, I have a tip that can help you improve your wi-fi signal. Actually, this tip is from Alf Watt. He created the popular iStumbler Wi-Fi utility and is a former Apple Wi-Fi engineer. According to Alf (reminds me of the old ALF TV show), it’s best to point one antenna straight up and have the other antenna parallel to the ground.

According to Alf, the perpendicular placement is best because radio reception is maximized when both client and access point have matched polarization (antennas pointing along the same plane). Some client devices have antennas in vertical orientation, some horizontal. For instance, the current line of MacBook have their antennas in the black plastic part of the hinge in a horizontal orientation. By pointing antennas vertically and horizontally, you’ll maximize radio reception no matter which way your device’s antenna is oriented.

I actually have three antennas on one of my routers. I wonder how I should point the third antenna. I’m guessing it should be pointed at a 45 degrees angle. Anyone know the answer?
