use a regular center fed dipole, with a balun, and you wont need a tuner
Well, if by "regular center fed dipole, with a balun," you mean a 1/2 wave dipole fed with coax (and a balun), the antenna will only work fine on a single band--on the band where it is resonant. That is, it will work great on 80 meters, but no place else. The one exception would be a 40 meter dipole which you could use on 15 meters, where it will be a 3/2 wave dipole.
As a practical matter, except for the 40/15 meter combination (and, maybe, just maybe, an 80/10 combination), a coax-fed dipole is going to limit you to a single band. If you want multiband operation, try a coax-fed fan dipole or use ladderline and an external tuner.
If you Google "$4 Special," you'll find a great introduction on homebrewing a simple, ladder line-fed antenna.
