A quick numerical calculation for squares of side 2cm with 3cm center-center gave me Z0=127.3 Ohms. This assumes perfect conductors. The approximate equation for large spacing is Z0 -> 120*ln(2*separation/(1.18*side)) and gives 112 Ohms; so it is about 10 percent off. I hope this helps, 73 Kevin w9cf _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk  |
