Sub-Standard Equipment Trends
• Increasing Attempts by Inexperienced Manufacturers to Try
Production of Transmitting VSAT Antennas
• Designers often unaware of how accurately installers must align
the antenna to prevent ASI and cross-pol interference
• Now, Auto-Deploy Is Being Added to the Mix
• Reduced Satellite Operator Provision of Type Approvals for
VSAT Earth Station Equipment
• Vacuum in Technical Know-How and Deployment of Systems
That Spray Orbital Arc with Interference
