  noise canceling Elevator /HF?

hi

I've had some interference from 1 to 30 caused by new elevator
equipment.

my building lookes like a long but narrow rectangle

it's about (rounding off) 100ft long maybe 50ft wide i'd guess

on each far end of the rectangle is an elevator room

both throw out same type noise

my antenna a horiz dipole center tuned (SGC) is ontop of the Eastern
one

some have recomended to help cancel the noise i try a noise
canceling device like a timewave anc4(others are simular so i'll use
anc4 as example)

i happened to have one hooked up anyway and already had a small
antenna extra up there i taped to the side of the elevator room it
picks up noise fantastic

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.

  Cobwebb antenna question?

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?

Many thanks
