Hi, all concerned: Does anyone have an EZNEC model file for the TH11DX, please? I'd like to see if it's worth the effort, to extend the log driven cell "out front" to 1 or 2 elements for 6M and "out back" to one element for 30M. Issues are the HyGain 4K balun at 6M, and the use of parasitics to manage feedpoint Z. Tia & 73, Dave, N3HE
