Antenna Question

[sivan_and]

well i have this external magnet mounted antenna for GSM dual band use..



can i use this with my Wifi router (Airlink 101 AR420W) to increase range therby performance..the sockets seems to be perfect fit !!! will there be any impedance mismatch or freq difference (ie wavelength) of the antenna..

Airlink 101 AR420W

I think frequencies are different and unsuitable..

i doubt it will yield any great benefits. you are frequency mismatched trying to send and recieve on a 2.4ghz frequency band using a 900mhz or a 1.8ghz antenna.

if you want a bit better directional antenna for your home just google biquad wifi antennas, there is plenty available online.

Try it. There are many wireless channels. Some are near 2.4GHz, so it may work well. Anytime you use a device for a purpose for which it is not intended, you are at your own risk.

that means thrz a risk of RF output stage of the router getting burned by impedance mismatch...will try to reduce the output pwr of router then connect and see thrz any increase in the signal strength at a distance..

This type of antena is Very broad band. It may be of some use, and the router will not be damaged. If it has the right kind of connector, give it a try, but the biggest question is weather it will even be the right kind of improvment. If you are trying to establish a connection to a wireless device and it seems like you are just shy of it working dependablly, this might put you over the top. If you want to improve the range in general, you may find little improvement. I repeat that you won't hurt the device. The wireless router is limited by regulation to a small porton of a watt transmit output and it can take a no load, or incorrect load without a problem. Just changing the location of the radiated source, (antenna on a wire) may be usefull. Be sure to play with the location of the antena. As I said this can be usefull when trying to solve a specific problem.

or i will cut the antenna to be as same length as the router...

Google for Pringles can wifi antenna. The GSM antenna should be useful just for the cable and connector.
