[TowerTalk] Radial length

[Alex Malyava]

there is an article (in russian - http://dl2kq.de/ant/3-33.htm) on
DL2KQ website with MMANA/NEC2 computer analysis of vertical of various
length like 1/8, 1/4 and 5/8 with radials like 1/10, 1/4 and 1/2 above
different soil.
Depends on your soil and vertical height there is different number of
radials of different length you need to put.
If you have, for example, 1/8 vertical on medium or good soil you need
more then 16...32 radials of 1/4 to work better than the same number
of short 1/10 radials.
