[Lowfer] RE: Worthwhile going to Shielded loop?

[Alberto di Bene]

Talking of tuned loops, are there any drawbacks in tuning the secondary 
side
of the coupling toroid transformer, as opposed to tune directly the loop
winding itself ?

This would have the advantage that, placing the, let's say,  1:6 (turn 
ratio)
transformer directly at the loop location, then bringing its secondary 
into the
shack via a length of coax, you could place the tuning variable 
capacitor in the
shack, without the need of remote control.  The capacitance of the cable 
would
of course be in parallel with the tuning capacitor, reducing the tuning 
range, but
this could be accounted for.

Another advantage is that the loop would be balanced, if the only connection
it does have is that to the primary of the transfomer.

I have to build a new receiving loop, so would like to hear opinions on the
above before starting.  Thanks.
