The ISS features four different vertical antennas on the spacecraft. The reason for four antennas is redundancy in case of an antenna failure. They are made of flexible metal tape that are coated in Kapton, a polyimide film that can withstand extreme temperatures. The antennas are designed to withstand kick loads of 125 lbs.
Very cool stuff here!
