For example, the cutoff frequency is fc = c / 2w, where fc = cutoff in GHz c = speed of light, 30 cm/ns w = width in cm So a box 4 inches wide would be fc = 30 / (2 * 10) = 30 / 20 = 1.5 GHz Here's a calculator that gives the attenuation at any desired frequency below cutoff: http://www.k5rmg.org/calc/waveguide.html

I downloaded the WDK and SDK and followed the instructions in  https://msdn.microsoft.com/en-us/library/windows/hardware/ff546236.aspx and am now able to use the B210 in Windows 10.  It's been a learning experience.
