Narrative:

We were approximately 3 NM southeast of jka establishing our aircraft inbound in the 45 degree entry to the left downwind for runway 27. We had previously broken off our approach due to traffic congestion and lack of separation. When attempting to re-enter the pattern via the 45 degree entry; a banner tow pilot passed about 100 feet directly below us in a perpendicular direction to our flight path. We never heard any of his traffic calls and by the time we saw him pass underneath us I took the controls and initiated a climb to increase separation. Banner tow operations are continuously in effect approximately 3 NM south of jka. When runway 27 is the active runway there is not enough distance between the banner tow traffic and the traffic flow into jka.
