How tall is your vertical?  I'm guessing that it is too short for 80m and 
that you'll need more than just ground radials to make it an efficient 80m 
antenna.

I finally put the antenna up. Set up the radial plate and ran 85' of davis 
bury
flex to the shack. The swr on 80 meters is 6.0:1 and on 40 meters it is 
2.4:1.
Making a contact on 80 1300 miles away my dipole fed with ladder line 50'
inverted vee did 1.5-2 S units stronger than the vertical. Now if a had a 
full
compiment of 60 radials would this bring up the signal with that distant
contact? Just want to make sure the radials will help also help the SWR on 
80.
With my tuner i can easily tune down to 1:1.1. thanks for any help.
