There are a couple of good articles on this subject by John Bryant with Bill Bowers and Nick Hall-Patch , VE7DXR and the other by Mark Connelly WA1ION which are worth taking a look at. The first article includes measurements from 100kHz up to 7MHz. www.dxing.info/equipment/impedance_matching_bryant.doc http://www.qsl.net/wa1ion/bev/bb_antenna_matching.pdf 73s Tracey G5VU _________________ Topband Reflector Archives - http://www.contesting.com/_topband |
