Looking for a way to reduce mismatch. thanks John ____________________________________________________________ Meet the Graviteers: Ezekiel Victor My name is Zeke!

The driven element of the M2 is a T-match system, which is originally designed for a balanced transmission line. I'm not sure what your specific problem is. ?You could mount some 5 suitable ferrite chokes over your coax feed?line at the antenna feed point. I use a T-match system for my homebrew 2M9 antenna as well, however I use it in combination with a 1:4 balun (0,5 lambda * Vf lenght of 50 Ohm teflon coax). You will have to adjust the shorting bars, but this configuration will provide an excellent impedance match. ?BRs Willem PE2WDO?
