A good rule of thumb is to double the number to see a diff.
so from 18 adding the number to 25 wouldnt be all that worthwhile
go to 36

there is a point of diminishing return and a lot of work to get there  
HAR

I have about 60 wires in the yard ,, mostly under 30 Ft and could see the
BW of the 
160 meter L get smaller as I added them ,, good indication that they are
doing something

use wire ,,I initially used chicken wire which rotted out ,, that would
depend
on your local WX Cdx.

My 2 C worth
