If I use a Budwig Dipole Center Insulator
(http://www.k1cra.com/images/products/original/299.jpg) for my random
length long wire antenna, should the length of the wire coming off each side
of the center insulator be equal?

My yard will allow me to have one side of the insulator about 200 feet long
and the other side only about 50 feet. Should I even mess with the center
insulator and just go with a random length of wire?

I am just running this into a DX398 for occasional shortwave listening.
Thanks.
