After the job done, let’s have fun !<\/p>\n

This loop antenna is composed by a bundle of ferrite rods, a variable capacitor and litz wire proper to the center portion of the medium wave frequency band.<\/p>\n

The following video is a demonstration of signal increase using this monster ferrite loop antenna. <\/p>\n

The shack located in Maric\u00e1, Rio de Janeiro, Brazil, a low noise site, lakeside, and near the open ocean. <\/p>\n

The GPS coordinates of the shack are : <\/p>\n

S 22.9320\u00b0
\nO 42.8691\u00b0<\/p>\n

The DX MW station is FIRS Falklands 530 kHz that could be heard loud and clear with the aid of the ferrite loop antenna.<\/p>\n

Falklands\/Malvinas Islands are located 1,500 miles away from the shack and according to information published on the net, the station uses a low power transmitter, and in spite of it’s own local programs, also relay the BBC World Services at 00:00 UTC.<\/p>\n

The Grundig YB400PE is a top performer on medium wave band, it’s very sensitive, has excellent image rejection, and it’s narrow filter allows good dxing. I have already compared both the classic Sony ICF-2010 and the Grundig YB400PE and results are very similar, specially coupled to loop antennas. The AM-Sync of the Sony is a must, but the better narrow filter of the Grundig (compared to the Sony’s stock one) sometimes makes the difference for DX.<\/p>\n
