A couple of years ago I needed a low power 50-ohm load to dissipate any
reflected power on one of the ports on the hybrid coupler phasing unit I
built for my 160m phased array.

I used twenty 1000-ohm 2-watt 5% carbon-film resistors purchased from
Mouser.  I sandwiched the resistors between  two small (about 2" x 2")
pieces of perfboard, soldered the resistors together and (happily)
measured 50.0 ohms for the parallel combination of the twenty resistors. 
I added an SO-239, and voila - a 50-ohm, 40-watt dummy load (I recommend
that the key-down power you apply should not exceed 20 watts to
carbon-film resistors).

This dummy load, which has a 1:1 SWR from .5 kHz to 30 MHz (as measured
by my Autek RF-1), came in very handy when aligning my K2.
