i want to use antenna as reciver to collect WIFI signal how can i do it and where to buy it ?
i have wireless router modem belkin i want to extend the signal to other building 100 meter away but its line of sight i tried to use linksys range expander but it didnt work that good so i returned it now i want to use antenna at that building so it can collect the signal so any one know antenna type that i can find in market that i can use for that reason
ok thats sound good but what kind of connectors i can use to connect this pigtail to my NIC (its built in my laptop) the only way i can connect any thing to it is RJ45 interface

I’m doing this myself right now on a much smaller scale. I’ve got about 100 ft. that is working well. At the range you say your going to probably use a unidirectional antenna. I recommend a Yagi antenna. Google it and you can get directions on how to make one inexpensively. You really should get a good client wireless router on the other end that has another antenna you can point at each other. You might be able to rebroadcast it at the remote site.
I’m doing this inexpensively with Buffalo routers that are running aftermarket firmware by DD-WRT. Its free and super powerful. It isn’t an easy solution to figure out, but extremely cheap for the alternative of buying $5000 boxes for each side. DD-WRT has a list of routers that their firmware works on so you don’t have to use a Buffalo, but I must say I’m very happy with the 5 I have running.
What you would probably want is a highly directional outside antenna, probably a parabolic grid antenna. You can get these for around $40-50, and you would want to mount it outside the building. You’ll need to punch a cable through the wall, and you’ll need to make sure that the cable has the correct ends for both the antenna and your wireless nic (Radio shack can probably help you with this). If a single antenna on the receiving side doesn’t give you enough of a signal boost you can use another antenna on the routers side. If you had the time and know how you could build your own "cantenna" ( like described here http://www.turnpoint.net/wireless/cantennahowto.html and here http://www.oreillynet.com/etel/blog/2001/07/antenna_on_the_cheap_er_chip.html ), but unless you have some significant radio experience the learning curve can be really high.
