The ground mounted 1.2m dish is currently dedicated to Inmarsat 3F3 POR at 178E. Winter is coming and so it was time to weatherproof and paint the 5-turn helical feed. The feed was also phase center optimized during dish calibration. The LNA is a Kuhne Electronic KU LNA 152 (but with a custom weatherproof milled case, with bias-T) and has a NF of 0.4 dB and 33dB gain.
The LNA is weatherproof by design but it never hurts to have a little extra protection. Here we have a nice half-pipe cover to keep water from hitting the LNA directly. The design was suggested by UHF-Satcom.
And here is an updated profile of the the ground mounted 1.2m dish.
