A few nice Ham Radio images I found:

S129-E-007227 (21 Nov. 2009) — Astronaut Randy Bresnik (near the Columbus laboratory), STS-129 mission specialist, participates in the mission’s second session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the six-hour, eight-minute spacewalk, Bresnik and astronaut Mike Foreman (out of frame), mission specialist, installed a Grappling Adaptor to On-Orbit Railing Assembly, or GATOR, on the Columbus laboratory. GATOR contains a ship-tracking antenna system and a HAM radio antenna. They relocated a floating potential measurement unit that gauges electric charges that build up on the station, deployed a Payload Attach System on the space-facing side of the Starboard 3 truss segment and installed a wireless video system that allows spacewalkers to transmit video to the station and relay it to Earth.
