I have made a similar coil--antenna with remote fine tuning --no
mechanical components, everything is going trough the coax cable

I have a FS700 sitting here, but no antenna. There should be other
signals than LORAN-C/CHAYKA available, such as DCF77, MSF60 and the 162
kHz signal from outside Paris. It would be pretty straight-forward to
put up a frame and make a number of turns of wire, and put a low-noise
amplifier up in the attic. What existing projects should I look at or
take inspiration from?

What is your loading on the coil? How many turns? Schematic?
I've seen this page many times, but I lack a little of those details.
I want to get a little more details so I get a better feeling of what
it takes.
As I want a broadband H-field antenna, I know that I need to do
resistive loading, but what is a suitable value?
I know that there is a benefit in putting a E-field shield on it, but
be careful not to close it as that would cause it to block H-fields.
Cooking up a low-noise amplifier for these frequencies seems
relatively simple, but it is always nice to see what others have done.
Cheers,
Magnus
