The good non-inductive resistors are made by Caddock Electronics. Available from some of the catalog dealers.

> They are undoubtedly wire-wound resistors and will have too much inductance to work well as a dummy load. The resistance is fine. If you have an SWR meter, check it with that. SWR below about 1.5 would mean it is usable. It might be OK on 160 or 80 meters but not on higher bands.
