Hi all

I have just modelled both the Slim Jim antenna and J Pole antenna using
MMANA-GAL at the same frequency (145MHz) all other parameter equal and was
some what surprised that they appear exhibit the same gain and radiation
pattern. Based on an article I read in a English magazine many years ago I
have always believed the Slim Jim had a slight edge over the J Pole.
Wonder if others had a similar view and if my modelling is correct are there
any advantages with the Slim Jim design?
