help with EZNEC and a parasitic vertical antenna
 

Hello All,
I looked through the past threads about an antenna article that
has appeared twice in QST. The last article appeared in 1995 and was
authored by Robert Wilson, AL7KK. I'm thinking of building this type
of antenna, but wanted to change the element diameter from 1" to 1/2".
I tried to use EZNEC, but I'm having trouble setting the parameters for
the antenna correctly. Could one of the folks out there with more
knowledge of the program than I help me see what the change in diameter
will do to the antenna characteristics?
