Any open waveguide will be an approx 10db antenna. Side by side facing up will work. Wet washcloth layers over the waveguide will work as an attenuators. A hand works well too. Like Lewis said teams of paper work. You can face them away from each other too. A single charcoal briquette is a good dummy load.
