10 $ WIFI 16dBi Super Antenna Pictorial

Step 7: Results:16dBi antenna picks up 21 ap's instead of 7 with the original antenna!

When using this antenna, you should be aware that this antenna has a lot of gain, but because of that, a narrow beam in which it has that gain. In other words, you have to aim it.

The 2 pictures show the number of accesspoints picked up with a normal antenna that comes with the wifi card, and with the 16dBi antenna after scanning it over 180 degrees. I didn't expect any accesspoints behind me so I didn't scan that, allthough I can't be sure of that. Anyway, you can see the new antenna picks up 21 accesspoints instead of 7!

Is it good to emit a signal with an Access Point or, is it only to terminals???

Nice, Try to track down LMR400 or even LMR100 on a budget for the cable, as it is designed for microwave use. Keep in mind that good cable can be a bit expensive, though it will cut down signal LOSS at 2.4ghz frequencies. Wrong cable can reduce the signal at the point of a standard antenna, or even lower.

here is another alternative, but the cable really needs to be replaced with decent cable. http://www.dealextreme.com/p/2-4ghz-8dbi-sma-high-gain-dish-directional-antenna-for-wifi-wireless-network-2400-2483mhz-32023

How does it perform? 100% SS is good so long as the signal quality is there to match, my digital tv recieves 25% signal strength but the signal quality is still 100%

So, this antenna is a beam that is meant to be used horizontally?  As I was reading the instructions, I was assuming it was an omnidirectional antenna, and the plate at the bottom was a groundplane.  No?  That's too bad.  I would love to have plans for a 16dbi omni.  The radiation pattern would obviously be very flat and squat, but I live in Florida where the land is perfectly flat, and my access point is on the 1st floor.

they have no signal change what so ever.
Seems that maybe this is just the sure size that is picking the signal, not that it is directional, or increasing db, if a beam it should have some type of side to side rejection.
