You are correct that GR-1089 is very vague on the requirement (something like "line of sight??"). Due to the final installation config, I would go with a 9' cable crossbar height and I have always seen at least a 6' cable crossbar length. Also, I would ensure that your crossbar and supports are nonconductive. 2" - 2.5" PVC Piping works well and is easy to work with. (plus, you can get it at the Home Depot). I have a great collapsible design that I developed at my last job; if anyone is interested, contact me off list and I can describe it to you.
