I have a Palomar Engineers 9:1 HF Unun for non-resonant wire lengths and trying to figure out what length of wire to start with for 160-10m. There are many different recommended lengths from several different manufacturers/expert and the lengths are different for each one. I do not have an analyzer at this point so measuring SWR is not an option. I can run up to 150ft easily.
For those of you with a non-resonant end-fed, what length of wire and counterpoise(s) do you find optimal for 160-10m?
