I haven't got an antenna analyser to do the above checks.
Do you have a SWR meter?
Hi Herbert,
Pass a wrap of wire around the material if it is a bar, or through it
if it is a toroid. Connect this to the output of the SWR meter. Hit
it with a short blip of power and note the SWR. You have the
multiple/divisor of 50 Ohms. Give it two wraps, or two passes and
repeat for more clues. Repeat at the frequencies of interest. Make a
chart.
Try to keep the power low and application short so you don't burn your
fingers.
