I have just measured my TX ant impedance(R term) and it is 120 ohm! much higher than I originally thought.It is of course all ground loss,I am using 3 ground rods close to the TX and the house water/mains system.I wonder wether anyone can offer me comparitive figs for impedance and details of ground systems?

To improve I will have to put in an awful lot of radials! or consider counterpoises.
