Directional antennas can help.  http://www.radiolabs.com/Articles/wifi-antenna.html

the one and only way to avoid 2,4 Ghz interference is to use 5Ghz frequency instead. As long as it is a bridge, you do not have any clients on it - so i reckon both AP's support 802.11a/n as well as 802.11b/g/n

Why 5Ghz: 12 - 15 non-interfering channels, whereas 2,4 Ghz has only 3 (1, 6 and 11), less non-wifi devices interfering

Why not 5Ghz: shorter range than 2,4 frequency, client compatibility if you plan to serve WiFi devices on the wireless medium

Hi,

you need to confugre auto channel assigment, and CISCO APs setting the best channel for coverage.
I advise to forget Directional antennas, because it is not helping you.... The best way to implement dual radios with 5ghz leg!
