Ku Band Fixed Frequency Magnetron & Reflex Klystrons

Ku is a satellite band and a klystron tube is related to signal forming and amplification. This is likely from the analog days of satellite distribution...most things have gone digital now. I couldn't even put a value on it...odds are the components for this item have long been replaced though. I used to work in tv...somits a thing there for sure with sat transmitters, and could have been military too, but that tech is 40 plus years old...unless you are shipping to Iran or Cuba I can't imagine it's a worry. Lots of industry has satellite gear too so it could from there too.
