Ok i'm a noob. I've been poking around for answers too so I understand this a little more anyhow.
I plan on mounting these antennas 4' apart on a rooftop mast.  I plan on using a supplied Combiner with the Clearstream 5 then after both leads go to the combiner where I will then run the combined coax stream to the house. Inside the house is where I plan to add the amplifier.  
Here's my map according to TVFool   with a 30' elevation approximate from the address ground level.
Looks terrible but I figure its worth a shot with these antennas.
Any other suggestions?  More height?
