I also own the MD ST-2 and was wondering if I couldn't connect it to my MFJ -901B. The MFJ 901B is a Versa Tuner box with knobs for Antenna, Inductance and Transmitter. You could possibly just buy one of these boxes, connect it to the tuner and run your own copper wire around the inside of your attic. There is a ground connection on the back of the box. Does anyone know about the MFJ?
