Hi Rick et al, Just reminds me of 3Y0X from Peter 1 Island in 2006. They used a 3 el yagi laying on the ice and had a VFB sig on 160 ...but calculations were made before they went to this distant QTH. Nice memory! 73 SM7BIC Len

Perhaps model it in some version of NEC and play with the ground constants until the modeling program agreed with the measured impedance and frequency?
