At the high frequencies you are listening to you can't expect to hear
much noise.

Complain only when you don't hear any signals.

To hear any signals both the receiver and antenna must be tuned
exactly to the same frequency.

How do you ensure that both are tuned to the same frequency?

By the way, the 1/5th diameter coupling loop is much more likely to be
working correctly than the ferrite ring method. There's no way for the
coupling loop to go wrong. It is more efficient too.

There's no need at all for the coupling loop to be made of coax. Just
a length of self-supporting wire is perfectly adequate. Best if there
is no direct connection to the main loop.

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.

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,
