Frequency Range
4G/LTE Systems: 2300–2700 MHz antennas (e.g., GL-DY2327V9014) ensure backward compatibility and cost-effective upgrades.
5G NR Deployments: 3300–3800 MHz antennas (e.g., GL-DY3338V9016) align with 3GPP n78/n77 bands for enhanced throughput and low latency.
Gain (dBi)
14–16 dBi: Higher gain antennas focus energy into narrower beams, improving EIRP (Effective Isotropic Radiated Power) for long-range backhaul or sparse rural coverage.
Trade-offs: Increased gain reduces vertical beamwidth (e.g., 7.5° vs. 15°), necessitating precise alignment for sectorized networks.
Polarization
Vertical Polarization: Dominates cellular systems due to compatibility with handheld devices and reduced ground reflection losses. Cross-polarization designs are rare in standard sector antennas but critical for MIMO configurations.
VSWR (Voltage Standing Wave Ratio)
≤1.5: Industry benchmark for minimizing reflected power (<4% loss), ensuring efficient RF energy transfer. Values exceeding 2.0 degrade SNR and throughput.
Beamwidth Optimization
Horizontal (90°): Ideal for 120° sectorization in tri-sector base stations.
Vertical (7.5°–30°): Narrower beams (e.g., 7.5°) suit long-range point-to-multipoint links; wider beams (15°–30°) enhance indoor penetration or dense urban microcells.
Radome Construction
UPVC (Unplasticized PVC): Selected for its dielectric stability (εᵣ ≈ 2.9–3.4), UV resistance, and operational resilience across -40°C to +65°C. Superior to ABS in hydrolytic degradation resistance.
IP67 Compliance: Ensures dust/water ingress protection for outdoor mmWave and sub-6 GHz deployments.
Structural Integrity
Aluminum Alloy Frame: Provides EMI shielding and mechanical rigidity, rated for wind loads up to 60 m/s (216 km/h).
Corrosion-Resistant Fasteners: Stainless steel brackets prevent galvanic corrosion in coastal or industrial environments.
