Since in Europe and Asia the band typically starts at 1810 kHz it's possible those RBN's don't scan below there. 73/Jon AA1K _______________________________________________ UR RST IS ... ... ..9 QSB

Perhaps a case of "need" vs. "want." If you want zero db power loss vs. perfect ground, then the far-right column in that chart applies -- which is pretty close to LaPort's finding (.4 vs. .5 wavelen
