Search the forums. It's been done to death.

 

No, there's not enough distance between them to work effectively... one properly set up will work fine.

 

How much distance is required?

 

That's quite a distance between antenna elements I'm not quite sure how you would hold them together and still be able to drive down the interstate.
I've always managed to get my elements 102 inches apart not that it's very critical for evening out a radiation pattern.

 

A couple guys on here have used a single dipole with decent results

 

@ 15 miles between elements this antenna would have to be 120 miles long so how would you propose to keep this thing elevated in the air without it falling apart?
Let alone driving down the interstate 15 miles wide between two elements you wouldn't even be able to fit under a bridge.
