Equipment Downtime

Failures and Spares: 

Failures and Spares Most failures are user or ship related Power outage, antenna repoints, gyro failure, unfamiliarity with gear, etc. Solution: Learn to work with gear and ship quirks Antenna pointing failures occur, but usually are not catastrophic Solution: Work with SeaTel and learn to work with gear/ship quirks When equipment dies, it is usually RF gear, despite it being the “most reliable in the business” Solution: Spare LNAs, depot converter and power amp spares in SD
