what should the impedance be? I thought I read somewhere ideally around 36-40 ohms...testing my new 30m vertical showed around 75 ohms, and mostly flat for 2 meg or more, which I seem to recall is really not the best...am I correct that while a wide bandwidth seems good, it really isnt, I think maybe its telling me the radial system needs improved?
