DX Engineering (and other sources) sell 300-ohm window line, which easily handles 1KW. It is better for TX use than the RS stuff that is primarily used for receiving applications. I have used the window line for years for an 80-10 meter doublet without problems. When the line gets wet minor retuning may be required, and loss is greater than that of true open-wire feedline.
