Made a TV mount out of an old satellite dish.
First remove dish and cut off L&B bracket.

assemble and mount
hang and adjust.
Already had all but a few pieces of hardware, so this rig cost me about $5. Much stronger and more adjustable than ones I saw available to hang from above. Still need to do some cable management, but planning to paint the room soon, so will be moving things around then.
