Re: [TowerTalk] Re: One more ground radial question

[Jan Erik Holm <sm2ekm@telia.com>]

Yes but 4 wl long you will start to "modify" the
far field and brewster angle would get smaller.
What you then did would not be relevant for anything
but your QTH, i e your type of far field...conductivity
etc etc.
If we consentrate only on the near field I still
wounder if you really can benefit much from haveing
more radials in one direction (i e 5 or 10 degree sector
forexample), I´m not convinced.
If so you could stretch the example further. Lets say
someone just likes to work one direction, he then
puts lets say 90% of the radials in that direction,
well well....no I´m not convinced.
