Default Cobwebb antenna question?

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.
