Jorge,


Together with LA7QI, I successfully installed this antenna (only 160m part
of it) at JW5X in February 2008.
If you check JW8AW on qrz.com, you will see the antenna on the picture. It
is located on the left side of the tower.
Both top and botton goes to the  pole on the left side in the picture.

This antenna was successfully used JW5NM (sadly SK), and by other DXpediton
since 2008.

In Jan 2009 a SM and OZ station activated JW on 160m and had approx 1000
QSO's in a week on this antenna.
(please come forward.....)

My best QSO on top band was w7 (oregon) from within the aurora
oval......with noise level S7-9.

LA5HE sponsored the copper wire used for this antenna. The same type of
copper wire used on L-antennas on vessels in the merchant navy in the good
old days. Thanks Ragnar.
