Cantenna dummy load suitable up to 30 MHz and up to 1 kW
The term 'Cantenna' originally referred to a product sold by Heathkit Co. in Benton Harbor, MI, USA. It was a 50-ohm resistive load used by radio amateurs.[1] However, in the more casual vernacular of the Do-It-Yourself community, it has functionally become a portmanteau of can (e.g. an empty Pringles can, see below) and antenna, since they're used to broadcast (and receive) signals, and not just terminate them.
