A "good" receiver would work well at LF off that kind of aerial. You must remember that these LMSs have no preselection because they are intended for measuring telecom line signals, not picking signals out of the wideband "noise" from an aerial. They probably only have one selective circuit in them, and then at the IF frequency. Once again because they are used for line work they do not always have the dynamic range of a "real" radio receiver and so will produce lots of intermodulation products particularly if you have strong local singnals anywhere between DC and 2MHz. For best sensitivity and freedome from extraneous noises you need to restrain the bandwidth from the antenna to just the minimum you need to receive, when using that kind of set. They can be good but your location may be very different in its noise/interference profile to other operators. Your "best" aerial will need to be chosed from the armoury or loops and wires and active antennas as the one that best deals with your local situation.
