AH-2b Mobile HF antenna will cover all bands from 7-54 MHz when used with the AH-4. 8.2 Feet (2.5 m). List Price: $379.00 What makes this antenna so expensive? Does ANYONE have one, or know any more about it. What gives? Is it a helically wound antenna and a thick inner element like the "other" expensive multiband mobile antenna? 73 David N1EA
