Worldwide Spectrums Allocation Poster

I came across a post on reddit last week that had a link to receive a free poster illustrating electromagnetic spectrum allocation, courtesy of a company called Textronix, a testing and measurement instrument manufacturer based in Mesa, AZ (no affiliation with me). It’s pretty neat – I received mine in the mail today and just wanted to share some pictures here:

I was going to share the link to order the poster when I started this post, but it looks like that link has since 404’d, likely due to the high volume of requests.  A downloadable PDF version of the poster is available here:

Thank you Radio Guy for the comment with a link to a similar poster by the National Telecommunications and Information Administration, sans any company branding.  I’m posing a very similar link here containing the most recent revision of the poster:
