VSAT antenna repairs involve fixing satellite communication equipment to ensure reliable data transmission. Marine navigation focuses on guiding vessels safely using GPS, radar, and chart systems. Marine communication ensures seamless connectivity between ships and shore via radio, satellite, or digital networks.

Size: Typically 0.6m to 2.4m diameter for VSAT antennas; marine navigation antennas vary by application.

Grade: Marine-grade materials compliant with IEC 60945, IPX6/7 standards for waterproofing.

Viscosity: Not applicable to solid components; hydraulic fluids in systems may use ISO VG 32-68.

Buoyancy: Antennas are non-buoyant; mounted on vessels with buoyancy ensured by the ship's design.

Material: Radomes: Fiberglass or polycarbonate; reflectors: Aluminum or carbon fiber; structural parts: Stainless steel (316L) or galvanized steel.

Frequency Range: C-band (4-8 GHz), Ku-band (12-18 GHz), or Ka-band (26.5-40 GHz) for VSAT.

Polarization: Linear (H/V) or circular (RHCP/LHCP) depending on system requirements.

Wind Resistance: Up to 200 km/h for stabilized VSAT antennas; marine antennas rated for Beaufort Scale 10-12.

Temperature Range: -30°C to +70°C operational; materials withstand -40°C to +85°C.

Corrosion Resistance: Saltwater-proof coatings, anodized aluminum, or AISI 316 stainless steel.
