Wouldn't the complete enclosure of the Al by the packing tape reduce, or prevent, air contact. I'm not saying I did that good a job of wrapping the foil, I was just concerned w/ protecting the foil from physical wear & tear. It should help, but I honestly can't say how much. The tape should help keep moisture out, anyway. SNIP That's what I mean by the difficulty of "maintaining good contact". Your system will work fine. For a while. I was going to use the antenna just for portable ops, and I was hoping it would last longer than "a while." Surely the larger the surface area of the contact, the longer before it fails to make contact somewhere. There's no reason not to use it, but be on the lookout for intermod and harmonics or noise in the receiver when the wind blows and jiggles it, and don't be surprised when it fails.
