    Looks like the next thing I am building. I love building antennas and tuning them will be the bees knees.

    Cant find a price anywhere, but does this look like it would fit our needs? 400MHz-6.0GHz

    I guess that this one will work with those on 2.4ghz and 5.8ghz

    You guys have the right idea! Just make sure you are in the coupling range. Ebay has ones that pop up cheap frequently. The .5-18GHz is unheard of. WOW! Mine is 2-6GHz. I think I got it for $65 shipped.

    The C-046-10 looks like it will perfectly cover our band. 10db coupling too, so it's easy to read! Any idea where we can get these? I check Digikey and Newark. Might try Down East Microwave and Mini Circuits.

    -Alex
    If it is broken, fix it. if it isn't broken, I'll soon fix that.

    If your spending $200 on parts for this stuff...why not just buy a Daiwa
