I made my first Cantenna the other day using a 4 " diameter  by 6 "
length
tin food can.
The gain was not great but it did allow me to focus the signal without
moving the laptop around and it did allow me to narrow down where a
signal was coming from which was difficult with just the laptop.

I struggled a bit with the tools and had to improvise a lot.

What tools do you recommend ?

Is there a tool kit on ebay I can buy ?

For my tin cantenna, I needed only a pair of pliers and a drill.  Pretty
straightforward.

Re: Tools to Make a Cantenna


do you have a photograph of the inside of the cantenna ?
where does the USB adapator sit ?

Sorry no photo of the inside of the can.  Read the article carefully.
The USB wi-fi adapter sticks into the can thru the drilled hole on the
side.  YOu calculate the distance of the hold from the end/bottom of the
can.  Then just stick it straight in, leaving the USB connector on the
outside of the hole.

If you do some googling on      "tin cantenna" USB
you should find more info.

I used the turnpoint calculator to decide where to poke the hole.

My main problem was getting the n connector fitted properly on the can,
I used the chassis mount connector and tried to solder it on but it
fell off and i resorted to taping it on using gaffer tape.

do you screw yours on ?

ps

i liked the plastic duct cover . i am trying to get hold of some now.

I used a 140 watt soldering gun, rather than a pencil type soldering iron.
Once I get a corner tacked in place with the soldering gun, I can fill the
gaps with solder, or at least seal all the way arond, if not all the way
out to the points.  I leave the N-connector oriented with two points
touching the can, adn two waving out in space.

I've read some about using screws.  You need to have the srew heads on the
inside of the can, in order to avoid inserting little tuning stubs into the
RF cavity, and unless you pad the corners of the connector with washers,
you will probably deform the can, which I presume is not good.

Probably but given that it's all "fun" I'll offer that in the grand
scheme of things, you probably won't see a huge difference.

There's a couple you could use, one which is the panel mount with 4
screw holes, that's easy as is the panel mount one with the single big
nut so just drill a large hole and put the nut on the other side.

Not sure what type of connector you have?

I am using the chassis/panel mount with 4 screw holes.
I may try the other type you suggested.

I am trying to find a suitable cover for the cantenna and likde your
kitchen ducting.

I believe it is also possible to cover it with PVC.

Can you tell me what I should search for ?

So far I have only come up with sticky back plastic.

Personally I wouldn't cover it in PVC, but rather use the 4" vent
ducting but to be honest, if it's a metal cantenna that you're making,
just paint it if you want to stop it going rusty. :)

Thanks even though the hosting co staff moved stuff around and have
buggered up the site a bit.  Haven't had time to sort it out.
