I'm in the process of planning for installing structured cabling into my three bedroom house (it has three split levels).

The wireless access point I'm planning to buy is a TP-Link WR1043ND which comes with three detachable aerials http://www.tp-link.com/en/products/details/?model=TL-WR1043ND 
 
I plan to have the wireless access point high on a wall in the top level hallway and was considering the worth in running an RG6 cable to that access point. 

My thought was to use the RG6 cable to re-locate one of the aerials for the wireless access point to one of the other rooms in the house, to increase the overall wireless coverage (or provide better coverage to an outside entertainment area when needed).  


Is this feasible or will such a long run for the wireless aerial be deterimental to the operation of the access point?
