Good morning LWCA,

As mentioned on the LowFER net this morning, here are some links to construction details for the active loop antenna. It should be adaptable to LF/MF with some adjustment of the coil and transformer winding specifications. It looks to be an interesting loop based complimen to the popular mini-whip antenna.

I hope this is of interest.
