I have thought of that many times. Those tunable loops(terk and grundig have them too), are coils tuned to the AM band frequencies and frequency adjustable for peaking. Isn’t it the same as the loading coil you construct for the outdoor antenna? I think if you inserted it between the transmitter and the 10 foot wire you would have better results….and you can peak it with the tuning cap and have a good indoor antenna.
Seems that this is a larger loop with less turns of wire as opposed to the one you construct around a 3″ PVC pipe….more turns with less diameter. End result inductance is the same and this is done for you already and is tunable. But with the talking house the internal Auto-tuning may not work if you do this.
Have never tried but on paper should work.
