Narrative:

While executing a banner pick up a combination of light gusting surface winds in combination with passing over an inactive runway on a hot day the airplane sank slightly over grassy pick up area and concurrently started to drift slightly left (from a light gust). The approach appeared manageable, however the left horizontal stabilizer struck the left pick up pole, creating a small dent on the leading edge. In the course of a banner pick up a brisk rotation is required for a clean pick up. This was the only option available and is what I did. It is possible that if the poles were spaced further apart the incident might not have occurred. After returning to the ramp I was informed that this was a very common occurrence. The only improvements that I could think of was if the poles were made of a rubberized tube of some sort striking the tip of one might not dent the leading edge. Spacing the poles further apart may help.

Title: MINOR DAMAGE TO LEFT HORIZONTAL STABILIZER DURING BANNER PICK-UP MANEUVER. STRUCK POLE DURING TEMPORARY LOSS OF CONTROL OF ACFT IN GUSTY WINDS.
