I realise that we will probably be off topic, but a 9:1 UnUn is often used in random length wire antennas for frequencies under about 1MHz. There are often various arguments for and against the 9:1 UnUn, some people preferring the 4:1 version and others saying the 4:1 doesn't work well for them. A quick google for '9:1 UnUn' will give quite a number of sites with designs and arguments about what type of earth connection/wire/antenna to use it with. Dave (G0DJA)
