It seems to me that there are several problems
with this antenna system.I am not refering to the DANGERS of the tower which do
seem to be troubling Mal.No I am more concerned with the efficiency of the
structure.For the following reasons:-
1) The use of 3 inverted L ants on the
same support will imply 3 vertical wires which will result in excessive capacity
to ground and indeed to the tower.This will mean more antenna current low
down,defeating the object of the high support.
2) The same applies to the sloping top
loading,as these wires approach ground they too will carry excessive current low
3)The use of radials only 1m above ground,this
will be self defeating since they will couple closely into the ground losses,
they could as well have been placed on the ground where they would not be a
hazard to people animals etc.
Finally I would have been concerned about this
antenna having such a high efficency (ie high radation resistance) that care
would have been needed to keep the ERP within legal limits,however the
construction as proposed is not in my opinion likely to be anywhere near as
efficient as it might be.73s Laurie.
