Re: [TCML] Re. Polythene dielectric.


It won't be lossy, it's good to use in that regard.  That tubing does
tend to shrink or expand with temperature so it needs plenty of
wire coating (polyurethane or whatever) to hold the wire in place.

Hello all.
I have a 54" x 12.5" yellow polyethylene tube (gas pipe) which I wish to use for 
the secondary of a largish spark gap tesla coil.
I appreciate that this is essentially a low loss material from the RF point of 
view but unfortunately it is very thick walled, 20mm in fact, this makes it 
pretty heavy. Does this thickness make it unsuitably lossy for TC use?
Suggestions would be appreciated,
