Things are gettung side tracked here. When I am experimenting I
measure capacitance, inductance and resistance against frequency where the totally resistive ponts are of interest. The standard resonant points will be low resistance and the anti resonance points can range from 50 ohms to 300 ohms and I plot these against frequency,. So a poster took issue with the 300 oghms with the suggestion that I advocated the use of 300 ohms connected to 50 ohms for transmission. That was a comment to bait and people started to bite at it especially when it was mentioned that 3/4 of the power would be lost. When all the data is compiled it then becomes useful with respect to antenna design. For measuring purposes it is only important that the anti resonant pont is resistive since there are so many factors that t can change the ohmic value in its final environment. It is then that you become concerned about the matching The poster mentioned a" system "in his evaluation which has no relavence to the project at hand, he only posted for baiting purposes and frankly his supplied figures was just a hoax or just a plain error that had no connection to the post I made. Art How are you determining the resistance values of a theoretical antenna? Are you using known resistance of various materials and assuming various resistive losses? Or are you using resistive terminations? I make an antenna and with a MFJ 259 I record the measurements over 30 MegerhzArt |
