How to build a tin can waveguide antenna
Assemble the probe and mount in can Now you'll need that bit of wire. You'll need a soldering iron or a friend with one as well. Cut the wire so that when it is stuck in the connector as shown, the total length of both the brass tube and wire sticking out past the connector is 1.21". Get as close to this length as you can. When you've got your wire correctly sized, solder it into the connector keeping it as straight and upright as you can. Connect your antenna to your wireless card or access point To use your cantenna, you'll need a special cable commonly called a "Pig Tail".

Can I use an inline amplifier with a 18dbi wifi antenna You have to be careful here, what you are doing *might* require FCC inspection and approval, assuming you're in the U.S. to make sure you're "certified" and not breaking the rules on power output. This is true even though it's in the unlicensed WiFi 2.4GHz and/or 5GHz bands. You also need to factor in how many dB loss the 30-foot cable has because this does come into play for your overall power budget. You didn't mention what distance is involved here. Yes, trees and branches will create scattering of the RF signal. Depending on the distance and if this is 802.11a or b/g you should look up "fresnel zone" and make sure you have a clear RF line of sight, with no more than 40% blockage of the first fresnel zone.
