Horizontal long wire MW aerial.

[Crackle]

I carried out some more tests with the new earth. Using my bench supply on an Isolating transformer, at 10v DC there was 1A current. giving a resistance of 10 ohms between the mains CH radiator and the new earth.
Being as the CH system is connected to the main house earth point, as is the mains water pipe, dose 10 ohms seem about right and suitable as an RF earth.

thanks
