Direct Calculation of Tuner Losses: Transcript

Dave Birnbaum K2LYV What Why Amateurs are using a huge variety of antennas these days Many of these need some sort of tuner to provide a good match to a transceiver With the availability of fast computers and antenna modeling software EZNEC 4nec many antenna designs can be modeled in detail which includes direct calculation of antenna impedance vs frequency. 1489 Vector Research 1061 Victor 1055 Vidikron 1047 1103 Vidtech 1004 1005 Viewsonic 1361 1489 1495 Viking 1100 Vizio 1489 Wards 1000 1001 1004 1005 1031 1044 1047 1048 1053 1056 1057 1059 1060 1061 1063 1064 1103 1118 Waycon 1085 Westinghouse 136 7 656 JPEG Encoder Scaler H264MPEG2 TranscoderEncoder SX3 1Gbit FCRAM CNRS-IN2P3.

Often derivatives can be calculated at fraction of cost of finite-difference derivatives. Goal of today’s lecture is to show why this is usually true for static response.
