+  - Cut all coat hangars to size (one for each director element, one with a gap for the dipole, and one long one for the reflector.
+  - Affix the boom in position (connect two 2x4's with another connector piece on the bottom if needed).
+  - Attach all director elements and the reflector using staples at the distances given by the Yagi design details.
+  - Attach the dipole and matching transformer with two small screws and washers (one washer under the dipole, one above, and one above the transformer, for example).
+  - Attach matching transformer to coax.
