Re: Cobwebb antenna question?

Question about the elements.

Does the speaker wire need to be kept very straight (no twisting) or doesn't
it matter if there twisted?

Thanks

Ok Dave, I will see what I have in the shed.
Trouble I have is that I only have a SWR meter to do the tuning and I
have heard the thickness of the wire can change the length of wire used by
quit a lot. So I really needed to get it very close for the tuning as I
don't have an analyzer to use.

Thanks

I'm in the process of building a homebrew Cobwebb Ariel.

I have found two different sizes for the twin cable elements, figure 8 42
strand 0.2mm, but on the Cobwebb web site it says figure 8 84 strand.

Also in the Cobwebb revealed PDF doc that I downloaded on page 5 it says
each core is 42 strands of 0.2mm diameter and on page 7 of the same doc
it
says figure 8 84 strand. So I'm a little confused.

Does anyone know what is the correct cable to use, 42 strand 0.2mm or 84
strand 0.2mm?

As I read it, this is two-conductor "zipcord" cable, with 42 strands
in each of two separate conductors, for a total of 84 strands.

I doubt that the wire gauge or strand count is very significant, let
alone critical. You could probably build this from whatever sort of
stranded zipcord-type loudspeaker or appliance-wire cable you have
locally available (as long as it's not too thin-gauge) without
noticing a significant electrical difference.
