Initially, I was confused about this.  To me, a "Cantenna" was Heathkit's name (in about 1970 or so) for a dummy-load built from a

1 gallon paint can with a non-inductive resistor inside, immersed in transformer oil, capable of dissipating 1 Kw or so.  

Showing my age.

Now, on Google-search, I see it as an antenna built with a tin can.
