4G LTE Antenna: High-Performance Solutions for Reliable Connectivity in Urban and Remote Areas- Our Technological Leaps
In 2023, a remote mining operation in Western Australia faced constant communication breakdowns due to weak 4G signals. After deploying RF element’s 4G LTE Antenna, they achieved 99.5% signal reliability, enabling real-time equipment monitoring. This article explores how our antennas overcome challenges like multipath interference, extreme weather, and long-range connectivity—backed by technical innovations and certifications like FCC Part 22 and IP67.
1. Technical Specifications & Design Innovations
Product: RF element’s 4G LTE Antenna
Frequency Bands: 698–960 MHz (Band 12/13/5) & 1710–2700 MHz (Band 2/3/7)
Gain: 5–7 dBi (omnidirectional), 10–12 dBi (directional)
VSWR: <1.8:1 across all bands
Power Handling: 100W (continuous, 50Ω impedance)
Environmental Rating: IP67, MIL-STD-810G (salt spray, vibration)
Key Innovations:
Dual-Polarized Design
±45° slant polarization reduces signal loss in urban canyons by 30% compared to single-polarized antennas.
Low-PIM Construction
Gold-plated N-type connectors and PTFE-insulated cables ensure PIM <-150 dBc, critical for multi-carrier networks.
Modular Mounting System
Magnetic bases (50 kg pull force) and pole mounts adapt to vehicles, rooftops, or industrial masts.
