    Alex, I emailed one of their listed distributors and also their corp office to find out about sales.

    I found some on the cheap on ebay but not sure about the brands though. Huber & Suhner for $9.99 and a Mini-Circuits for $24.99

    For SHF they cost thousands of euros/dollars, but maybe I am wrong, I am going to check!

    Because the Daiwa is only good up to 1.3GHz. If you get the SII it is only good to 2.4GHz and will run you $350. You can't do 5.8GHz because a 5.8GHz SWR meter doesn't exist. With this thing you can spend $60 and use a cheap multimeter. I am still working on a DIY directional coupler. Stand by

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

    I need more data before getting the diode. Will any microwave detector diode works?

    Looks like digikey has the microwave diodes in stock: http://search.digikey.com/ Type in HSMS-286. Then select anything. Single will be easiest but a dual isolated pair works too. That's what I used.

    And the datasheet: http://www.avagotech.com/docs/AV02-1388EN
