Stock antenna are 4dBI and i get really good range. I also have a pair of 2.4GHz 5dBi Indoor Desktop Omni-directional Antenna TL-ANT2405C http://uk.tp-link.com/products/details/?categoryid=217&model=TL-ANT2405C

Thats 1 dBi gain over stock and does yeild a little more range.

The problem is with these 2 15 dBi's my range is half of what it was, no gain at all just pure loss!!!

Why?
 
Pete you would have been better with there 8dBi indoor antenna that fits on in place of the stock antennas.

These to get the performance need to be mounted vertical and AWAY in clear space from any objects. Mounting them so close to a wall will degrade the return loss to the wireless transmitters in the AP.

Awaiting for my cables too arrive but there RPSMA-N Females where to hand.

If i bang it up in the attic in the middle they will be okay and better?
 
Yea should be better and the spacing will just have to be a little trial and error.

Start with them about 2 feet apart Pete and go from there as the software the router uses will or should be able to calculate the distance the antennas are apart and thus adjust the phasing of the signals to create an array from this info.

Don't forget though the maximum radiation from the antennas will be greatest at an elevation equal to the antennas as there is very little radiated signal below the antennas. As the radiation pattern if you could see it, looks like a large doughnut shape at 90 deg to the vertical plane. With the antenna passing through the hole in the centre.
