Find the null frequencies of a known length of the cable as a stub, then do the arithmetic. Try to make the measurements at frequencies near where you want to use the cable, because Vf varies a bit with frequency. An analyzer as simple as an MFJ works for this. 73, Jim K9YC _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk |
