Re:40M antenna survey - 2011/03/11 11:10
Hello Roy
Your website is VERY interesting and reading it will keep me busy for the next few days.
Glad to see people using the compex number facilities in Excel to solve some impedance related problems. I made a spreadsheet using complex numbers to calculate the matching stub of a 40m EDZ. By the way those 450 Ohms window lines are below the advertized 450 Ohms. This figure is more of a generic name than the real characteristic impedance of the line. I modelized the antenna with MMANA and imported the R + jX *.csv file into my Excel worksheet to find the optimized stub length. The antenna worked very well.
Your CVA antennas seems very promising and I will give them a try.
Thanks for sharing your work with us.
