Default Magnetic loop antenna ( again )

Hi guys,

I started a topic regarding magloop antennas few weeks ago asking about
ways to replace the ferite coupling method. Some hams, to whom I deeply
thank, have replied to the topic and provided some valuable insights on
the matter.

Since then I managed to "build" an acceptable antenna. The only problem
with it is that it doesn't work. yet, that is. HI!

Here's what happens : the moment I plug it into the FT100 ( both wires,
not only the central conductor ) I get silent background ( low level
noise ) as if it had no antenna at all. An uneducated guess of mine
would be that maybe the feeder shorts *before* the coupling loop.

Here's a link to a page describing the way I did it which contains a
small picture gallery of various parts. http://benny.kappa.ro/antenna/

Perhaps someone could enlighten me by providing any debugging tips and
tricks. The downside is that I don't really have any specialised
testing rig. I only own a multimeter, the ft100, the mfj in the picture
and a soldering iron :]

Thank you for your time,

73 de YO8SSW
