Hi, Jim;
If your are working HF, a few 2 watt carbon comp resistors in parallel 
will work  Put them in a can if shielding is required, but derate the 
dissipation somewhat and consider heat sinking them.  I made one by 
soldering resistors between the center conductor of some RG-8 and two 
pigtails of the braid.  It gives low SWR even at 2 meter frequency.  I 
didn't shield it and I never apply power for an extended time.
