antenna

I have a wireless G setup with a linksys router. I used to use a range
extender but it gave me problems so I would just like to put a super
powerful antenna on my router. Can this group reccomend something to
me. Thanks

How much of a range extension do you need?
How super powerful does this antenna need to be?

I like the http://www.freeantennas.com EZ-12 Windsurfer, but you might want

or maybe
http://www.nodomainname.co.uk/parabolic/parabolic.htm
both based on the EZ-10.

CompUSA sells the "Cantenna", which I find pretty funny. You can make
it for something like $5 after a trip to Lowes (hardware), RadioShack
(electrics), and the Grocery Store (can of Pringles), but it's like
$30 at the store.
This type of antenna would be used for extending your range in a
particular direction, like to reach a friend's house or nearby coffee
shop.

Linksys sells some longer antennae that connect to their router/AP
models.

good luck, and let us know what works best!

I am on the 4th floor and need it to go straight down to the 1st. It
makes it to the second. I would rather buy one then build. Should I get
the cantenna ?

Trying to go down through floors is very difficult. The signal will likely
die trying to go through the brick, wires, pipes, concrete, etc. that
will get in its way. If the person is directly below you, I recommend
going out the window, down, and then back in from his window.

A directional antenna like the cantenna would be what you need. You lose
signal gain (is that the right terminology) by using panel or omni-
directional antennae.

hope that helps.

The Cantenna is an excellent choice, but a Pringles can is just a bit too
small in diameter. You would do better with a 3.25" inside diameter can from
26oz Bush's Beans or Del Monte Spaghetti Sauce. Some of the Campbell's soups
come in a large 26oz can, also. You can buy the cheapest or you can buy what
you prefer to eat - - your choice.

You have to drill a hole in the side of the can exactly 2.49" from the
bottom end of the can. The diameter of the hole depends on the connector you
have. For a single-hole BNC or Type N, use 3/8", and if you have a taper
reamer, it's best to start small and ream it to size.

Then you need to solder a wire into the center pin of the connector - - use
any solid wire that you can find from 14 to18 gauge (I like to use the wire
lead on an old but unused 2-watt resistor). Cut any convenient length over
1.5" and solder it in, then cut it so that only 1.31" projects straight up
out of the metal body of the connector - - that's 1/4-wave at 2.4GHz. Then
bolt the connector into the hole in the side of the can and connect up the
cable to your router. Point the open end to where you expect the signal and
see if that doesn't improve the hookup. Don't use a very long cable, or else
all the good work the antenna does will be undone by losses in the cable.

Good luck,
