[amsat-bb] Other Sat ants

I was wondering is there a small 144/435 antenna? I'm open to ideas, trying to come up with something simple cheap and fast. It would be put at the 20ft level on my tower. At 25 ft level is a 9 el M2 2m yagi but its not at a angle. I like the Elk cause it only has one feedline but would not want to mount it outside permanently.
