Hello, Need your help. For a long time can't get working FCP for my Inverted L. I'm looking for some way to check quality of my homemade isolation transformer. I'm connect primary to 50 Ohm dummy load and secondary to Antenna Analyzer. Get reading @1850 Ra=28 Ohm and Rx=34 Ohm. Rx is raised with frequency. Inductance for primary and secondary is 5.7uH. Capacitance between primary and secondary is 140 pF. These reading looks normal or somthing wrong ? I'm expected 1:1 impedance transformation without additional Rx. Thanks a lot in advance for your help. Regards, Andy - YL2QN _________________ Topband Reflector Archives - http://www.contesting.com/_topband |
