Dear Wolf,
 
The Crawley Club have a quantity of "HF" Litz wire available with different diameters and number of separately insulated strands suitable for making high Q loops.  Probably the best would be the type with approximately 2mm diameter which has about 140 strands and double silk covered. The cost of that is 2.0 UK pounds per 10 metres plus postage cost.  You will probably need around 100m.
   The club did have some 2mm diam Litz with outer polthyene weather proof plastic covering but that has now all gone.  Contact me if you wish to obtain some of the Litz

Subject: LF: Source for Litz wire at the Ham Radio ?

Dear LF group,

for an active or passive RX loop antenna (G3LDO design or similar) I am
looking for the "Litz" wire mentioned several times on this reflector.
As far as I understood, it contains a number of thin copper wires
electrically insulated against each other to reduce the skin effect.
(BTW in DL, when you order "Litze" you just get flexible wire for
installation purposes. An other kind called "HF Litze" is very expensive,
very thin and sold in lenghts of a few meters only).

Has anyone ever compared the Q factor of a loop antenna built with Litz wire
to one with simple stranded wire ?

Any possibility to get the "good Litz" at the Ham Radio in Friedrichshafen ?
