Interesting idea. I'll have to ponder it a bit before I can make a meaningful comment. It does appear to offer some promise. One thing to keep in mind is that a number of locations prohibit a "mast or tower" of any kind.... thus using it as a dipole might work technically, but not be usable in the field. We actually made one like that, and went back to the solid disk. While it was lighter, it had tendency to get hung up on other stuff in the backpack. Thanks for the ideas. If you build one according to them, I'd appreciate your posting them. I'm always interested in better / handier portable antenna systems. They make field work a lot more fun.
