Here is an easy 50-ohm 2-watt dummy load for QRP ham radio service. Two 100-ohm 1-watt resistors in parallel make the circuit. A core of a scrap of RG-58/U coaxial cable forms an insulated wire down the center. A 140 watt Weller soldering gun was used to "tin" the metal barrel of the connector. The insulated wire was inserted (after it cooled!) with a 15-watt iron.
These are in my Flickr set "Amateur Radio QRP 2W Dummy Load".
The pen points to where the base of the connector was "tinned".
