I've got a dog fence underground wire (surrounds about 4-5 acres) that I've been thinking about pressing into service as a loop underground (LUG). I actually have some RG6 running up to where the wire connects to the dog transmitter, but I haven't done anything. I did get some binocular cores to make a 9:1 transformer, but just haven't gotten around to it yet. But I'm wondering since I live in the boonies and the noise floor is so low here I may not get anything from it. I tried a small loop once and that was a total failure compared to my 65' dipoles and H DoubleBays. Noise floor level is not an issue for me.
