The now decommissioned NDB IPA-280, location Easter Island in the Pacific, distance 13000 km, has been received in Europe by only three listeners. The first was Vincent Lecler from France, who used a beverage on ground for antenna. The second was Hartmut Wolf from Germany, using a K9AY. The third person was yours truly, who used a mini-whip and the station identification was acquired by aural copy of the CW ID. This shows that very different kind of antennas can provide excellent results. The point is, what kind of antenna is the most suitable for your location? Loops are excellent, but still worthless at my home location, due to a radiating underground cable TV distribution cable. There is more to reception antennas than a simple A versus B test!
