Sure. How about mounting the antenna at the top of one of your trees?
Single trunked trees work very FB for yagi installations. I've installed a

of yagis - including 2L 40's - in trees over the years and they work like
gangbusters - no steel tower, no guy wires; electrically they're floating in
space!
