Seems like a VLF LISN for below 150kHz might be what he is looking for, asking about?? Just guessing?

VHF is typically 30 MHz to 300 MHz, and an LISN is a device to stabilize the impedance of a powerline to the EUT. Traditionally, an LISN “decouples” itself from impedance control when the length of the powerline to the EUT is about 1/8 lambda or more. Current standards recognize this by defining a powerline length of 1 meter and an upper measurement bound of 10 MHz. Keeping to this philosophy, a 300 MHz LISN would only allow for about a 3 centimeter long powerline. I think you need to clarify what VCCI standard you are trying to work with.
