[80m] Increasing ?

[PY2YP]

Hello,

I do have a problem that, due to a lack of knowledge, I can't find the =
solution.

I did measure the 4 towers of my 4 square when they were not phased, =
e.g. them all were disconnected, and fed each one at a time to found out =
the following VSWR values:

Tower 1: 3.800  1:1.41
Tower 2: 3.800  1:1.59
Tower 3: 3.800  1:1.54
Tower 4: 3.800  1:1.48

I have a spreadsheet (57 kbytes) with the complete measured values and a =
graph as well.

All towers have an aluminium tube at the end which allows to either make =
it shorter or longer. The question is: based on these values how long do =
I have to increase each one, e.g., towers numbers 2, 3 and 4, in order =
to have them all set to the same VSWR value, I=B4d say 1:1.41.

I have a spreadsheet (57 kbytes) with the complete measured values and a =
graph as well.

Thanks in advance for any help.
