Hello Group, Hi Dick, Question to PA0SE: Dick, did you choose 1.5mm of diameter or radius? Some programs are using "radius" other "diameter"... Here are the results from simulations with MININEC algo

For those who do not have acces to antenna-software there is still the possibility to calculate the radiation resistance and the capasitance of the antenna yourself. If a simplified model is taken an

Hello fellows, first of all thank you Dick and Peter for running all those simulations. Again, I have learned a lot. Refering to the last part of my second report (16.9.99 14.17) it is clear that top
