VHF, UHF, and All That


Here's an excellent post over at the K0NR web site spelling it all out.  Also, here's a good graphic summary:


Nice use of a log scale on the x-axis.  Makes things more intuitive.

To help non-technical folk orient, the AM broadcast band is just off the left side, the FM broadcast band ("3 meters," although no-one ever calls it that) is smack in the middle tucked between the 6m & 2m bands, and bubble-pack FRS walkie-talkies slide into the gap between 70cm & 33cm.
