If you have the inclination, some 300 ohm twinlead, a 9:1 balun and a Wellbrook loop outside, you can use that Wellbrook on any regular radio in your house with inductive coupling.
I discovered this by accident.
My old tube table radio is on the far side of the radio room. I was running a feed for it from my antenna switch that goes up to the loop on my roof. I ran 50 ohm coax off that switch to my PAR 9:1 box, then to 300 ohm twinlead which was on my floor in a looped pile waiting to be cut down to the length needed for the feedrun. I had the radio on tuned to a MW station, and the loop's power was already on. As I connected that feed system onto the loop's switch, that radio came alive!
I doubletaked at that 300 ohm bunch setting on the floor about 8' from the radio and immediately realized major inductance. Picked up that pile off the floor and shoved it behind the radio and boy talk about potent reception. Tuned around a bit and it was getting distant stuff as I would if it was directly connected to the loop.
But I wound up direct connecting anyway because that old radio has shortwave inductance won't work there.
Just thought I'd throw that out there for some to try.
