SMILE Radio Amateur Antenna
The Reindeer antenna is currently under development. It will be installed in the ESA Kiruna station (Sweden), allowing to increase the support for polar orbiting missions in UHF and S-band.
Unlike ESOC-2, this antenna will support both the amateur UHF band (435-438 MHz) and the commercial UHF band (399-405 MHz).
