Simple Attenuator
Whitey promises that the attenuator can be built for under $3 while providing 60, 120, and 180db of attenuation. The scrap PC board material can usually be gotten pretty cheaply at a flea market. The resistors are from Radio Shack, and the coax and hardware come from a well stocked junk box. It's another solid design from the shack of K1VV!
