I've looked at this article but i wonder if using 4 inch copper flashing spaced at 1/2 inch in the vertical helix, the total length wouldn't add some considerable bandwidth.

Post by: AF9J on January 01, 2008, 03:57:53 PM I made a 1/4 wave (of wound wire) version of that antenna in college (got the design from an early 70s Handbook). It actually worked pretty well on 160m, with the FT-101B I had at the time. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
