The measurements in the booklet were taken from an actual cobwebb.

The lengths and tapping points for the Tee match, need to be adjusted
during the initial tests.

An Antenna Analyser is very helpful during set-up and you may have to
beg or borrow one for testing.

However, in tests, the following dimensions have been used
successfully:-

Band Element Length Shorting point
10M 2540 mm 1560 mm
12M 2930 mm 1790 mm
15M 3450 mm 2080 mm
17M 4060 mm 2220 mm
20M 5150 mm 2720 mm

Hope this helps

Steve.

Hi Steve
Do you have the correct measurement for the 17m element?

A lot of people say 4400 is incorrect as its too long.

Many thanks

output.

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?
