A Cirrus pilot departing a non-towered airport reported a NMAC with a helicopter.

Narrative

Two incidents happened within a short time of each other.A near miss with a helicopter. After departing ZZZ from runway XX; We first saw the helicopter with ADBS traffic alert and began looking outside for it. When we saw it; it was directly in front of us about 200-300 above us and about 1000 feet laterally. We passed beneath it realizing it was close.We proceeded to ZZZ1 for traffic pattern work. We joined the left downwind for runway XX and did two landings to a full stop. We noticed that the wind had changed to favor runway XY so we switched to XY on the ground and did two landings before departing to the south. During this whole time we were broadcasting our intentions but realized that we were on the wrong frequency and changed to the correct one around the time we switched runways.We noticed there was other traffic using XY while we were first using XX. However we continued to use XX because the AWOS clearly showed XX to the best runway for wind at that time. Later in the day we found that our radio silence had rattled nerves and caused problems for the flight school. We spoke to the flight school manger and offered our apologies for causing a disruption. There were no close calls or issues other then no communication that we observed.
