    Hi Don, no, but a couple of years ago, I Googled this and found a website or 2 that gave the info and directions to build them. Today I just found a soup can version of one: http://www.turnpoint.net/wireless/cantennahowto.html

    But these days, lots of vendors seem to have them for sale. Do your devices have connections for external antennae?
    How far do you need to reach? N, G?
    I am definitely not a pro plumber, but I am a pro crastinator

    Thanks Bob.

    Yes most good wireless device have connectors. (Until they get outlawed)

    I was building mine using Cans. So far I can get ¼ mile range but would like to make it better.


    The price is to high for the built ones, When We have the Technology...


    Thank You. I will check that site out. Have a great day

    CanTennas are more hype than substance. If you want to build a good highgain antenna and have an old sat dish kicking around, try this:

    That said, the quality and length of the wire and the entrance protection for the coax makes it impractical in most cases. I just use outdoor radios that many WISPs use.

    Very Nice. That's what I'm talking about.


    Thank You.

    I would like to do dual band N, but building a 2.4 Gig is tricky enough. But 5 Gig would be nice.

    The 2400 Mhz band is getting very congested. And Microwave Oven interference sucks.
