We were departing DFW around XA:30 local off of Runway 36 right; climbing through about 550 feet AGL I noticed the radar altimeter started to bounce up and down oddly and then I received a red RA and which is came back at around 1000 feet AGL and functioned normally until we reached the limit of the radar altimeter. I noted it to the Captain and he didn't see any issues on his side; however we were aware of the 5G NOTAMs and I had mentioned that might be the cause. That was the only time we noticed and issue; coming in from ZZZ it functioned fine and landing in ZZZ1 it was functionally normally as well.
Air Carrier First Officer reported an erroneous radio altimeter after takeoff and during climb out from DFW. The First Officer also reported they had reviewed the NOTAMs referring to 5G interference at this location.
