Just curious, what is a piston attenuator? For the life of me I can't seem
to picture it. I know how a slab of resistive material inserted in to a
wave guide works as an attenuator, but how is it accomplished in a coax
transmission line? If someone has a photo, or diagram of the inner workings
that would be great!

What you need is a standard Piston attenuator whose performance is
largely calculable. Forget about dinky wire-ended resistors whose
performance in attenuators is a matter of guesswork.
