Sectoral Antenna Maintenance | 7 Base Station Fixes

Maintenance of satellite parabolic antenna includes special inspection of WR-15 flange sealing surface (aluminum chips > 50μm will create VSWR > 2.1), substitution of the polytetrafluoroethylene support ring with a torque wrench of 35N·m (the dielectric constant must be maintained at 2.1±0.05), and helium leak detection according to MIL-STD-188-164A standard (threshold 5×10⁻⁸ atm·cc/sec). After level […]

What is the difference between horn antenna and parabolic antenna

Horns give 22dBi gain at 12GHz with ±15cm installation tolerance, while parabolic dishes are capable of 38dBi gain but require surface accuracy <λ/16. Parabolics demand ≥2D²/λ far-field test distance, while horns have ±3λ axial deviation tolerances. Phase drift: 0.15°C (horn) compared to 0.03°C (parabolic with CFRP). Principle Comparison Last year when we were debugging AsiaSat
