- Band width is great, gain is less than a monobander, and you can get a wide range of bands on one antenna without traps. 73 Roger (K8RI) _______________________________________________ ______________

- Mike: The way a log-period works is the element lengths are such that a couple are near-resonant on the highest frequency of interest, e.g., 29 MHz and a couple are resonant on the lowest, say 14 MHz
