Another option, using thin film resistors on a large air-cooled
heatsink:

This is actually a 30dB attenuator, so 1kW input delivers a 1W sample at
the output socket. This can be very useful for measuring the power with
simple test equipment, or for harmonic measurements. If you're building
a dummy load, it's well worth the extra effort to make it an attenuator
instead.
