Actually a properly designed purpose built loop can offer a reduction in noise from the high Q selectivity offered.
That would only be true if the receiver system noise bandwidth was wider than the loop's bandwidth. If you had a SkyBuddy with 30 kHz noise BW and put a 5 kHz wide loop in front, then you would have a noise BW limited by the loop.
The only way antenna BW reduces noise is if the receiver is overloading from out-of-band signals, or the receiver's ulitmate selectivity is wider than the loop antenna.
While an SX99 or something that terrible might benefit with a high Q loop, even an SX101 would not.
