Just keep in mind that if the loop is made in a square, it'll be about 9 feet on each side. the tuning range is unaffected by the receiver input impedance and the “Q” of the loop (sharpness of tuning) is not reduced, as would be the case if the receiver were connected directly across the main loop/tuning capacitor assembly. At this point it's worth noting that the magnetic loop antenna is a resonant tuned circuit and the RF voltages across the capacitor and the RF current flowing through the loop should be very high if the losses are low. Feed it with 300 ohm twinlead, make the legs out of #18 black insulated wire or similar, and you'll be surprised how invisible it is to the non-ham.
