Jean Claude's (a member of F5KCK) L-band dish for NOAA HRPT

SQ6EMM's 1.4m, f/D 0.45 dish

DL1EMA's 1.2m, f/D 0.45 S-band dish for QO-100 uplink, mounted on his home made AZ/EL rotator. Septum feed is supported by back-structure reinforced with alminum square tubes.

F5AOL's 1.8m dish for:
- reception of the hydrogen line at 1420MHz
- EME reception at 1296MHz
- QO-100 satellite uplink at 2400MHz 500mW
- portable contest operation at 1296 and 2320MHz

Fong Zi Hao's 1.4 m, f/D 0.345 1.42 GHz dish for the hydrogen line project. His received and processed astronomical results are here.

F4IKX's S-band 90cm dish for QO-100 uplink.

DL7HAR's 1m, f/D 0.45, L-band dish. The geodesic dish is mounted on a smaller offset dish so it is more stable to attached to a rotator.
Alex writes: I plan to use the antenna on 23cm and hope to hear some Q65 signals from the moon. And also for the uplink to QO-100 on the 13cm band. Currently I am using a helical antenna and it will be interesting to compare the performance with the dish. With QO-100 WebSDR the signal reports can be easily read.

　Ken's 1.42 GHz dish for the hydrogen line project. The dish is mounted on an equatorial telescope mount, equipped with a finder scope.
