If you modeled in NEC with stepped-diameter correction to get an equivalent uniform length and then took a percentage before changing back to tapered, you might get there. But if you can model in NEC, why not just work out the change there? And how accurate does it have to be? _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk |
