Ron - This is not an area where I have much experience, but with 450 ohm ladder line I would have thought you would use something other than a 1:1 balun.
A few years ago I experimented briefly with an 80 meter dipole, fed with 450 ohm ladder line. I tried it with a 1:1 balun and with a 4:1 balun. An LDG AT-7000 tuned it very easily on 80 through 10 meters while using the 4:1 balun... but had trouble on some bands with the 1:1 balun.
