Hello Folks,

I have a couple of questions pertaining to Litz wire and my loop.

For receive in the LF bands I am currently using a loop that is 2.2 meters
on a side and wound with #16
wire 30 turns to be exact with a spacing of about 12mm..  That along with
about 100 pF allow the loop to resonate at approx. 180 Khz.  The loop is
excited by 1 turn of the same size wire.

I decided 1 day to try and transmit into this loop and found that with .5 mW
at 5 KM there was an easily copied signal at QRSS30. This loop is fed using
about 110 meters  of category 5  balanced 100 ohm computer networking cable,
and a 16 to 1 transformer (located in the house) to approximately match the
75 ohm transmitter.

This loop was about 300mm above the ground.   I raised the loop to about 1
meter above the ground and the tuning was sharper and the signal strength
was slightly stronger. The loop is 110 meters distant in the woods
surrounded by trees. (No leaves now)

Here are my questions.

1) Does this "high impedance antenna?"  suffer from the same problems as a
high "Q"  vertical such as absorption from trees, ground etc?  So that
removing it from this environment might increase signal strength?

2) Would I benefit from using Litz wire?  I have a quantity of  45/#36 litz
that I could rewind the loop with?

3) Does higher "Q" neccessarily mean more radiated signal?

4) In most cases I don't belive we want the coil to radiate but in this case
I wasnt to increase it. Any ideas on how to do that?

Any help would be appreciated

Thank you
