I don't know about the MFJ dummy loads, but I would get low powered air cooled load for it. I use a 25 watt air cooled that I got at a ham fest for most of the testing here. Beware and take an ohm meter with you if you plan to buy one at a ham fest. Not long ago I bought what I thought was a 50 ohm 300 watt air cooled dummy load. When I got it home it measured 78 ohms.
