40 watts on two meters. It's hard to see here, but the "transmission line" is two parallel copper pipes (from the camera angle, it looks like just one). That makes it a balanced line, about 200 ohms. Bill says that all the principles he demonstrates apply to (unbalanced) coax as well.
Oh, including valleys. And the nulls are the zero crossings. Duh. (For some reason i was thinking the nulls were the valleys. Now i'm wondering where the hell my head was at.) Thanks. ☺
THIS IS COOL.... Every ham should see this....

I wonder how much RF energy was used in this demo and at what frequency.
Very Interesting video

In that case i must misunderstand something, as i was guessing a little under 300 MHz, based upon the 1m or so spacing of the peaks.

The peaks happen at the half-wave points, so about 1 meter for the two-meter band. The complete DVD explains it pretty well.
