Wa5vjb specked out a 435 antenna Just keep looking there several
places on the web the have his antenna's
it is on the bottom of the page on the web site I just looked at.
I built a set the 5 element 2 meter and an 11 element 435 used them
for about a year before I went to the Gulf Alpha Cross
I am using now. I made several hundred contacts with the setup. worked well
