Hopefully this url will get you to what I want you to read.
Read, think for your self and then decide why the use of
aluminium is relavent to our hobby. I have also placed an
abstract on the forming of radiation on E Ham forum to get
as wide a distribution as I could. Hopefully this will a new
beginning for ham radio. Also get an optimiser computor
program to obtain the tipping angle of a radiator for your self.
Google for information every time you are unsure. For goodness
sake don't guess but follow the lead of present day science.
Somebody will burst out without reading or thinking.
Is that person going to be you?
Very best regards
