Product Description
The RF1742-9030D 900mm parabolic antenna is designed for wireless communication systems requiring higher gain and long-distance directional coverage.
Operating across an ultra-wide 1710–4200 MHz frequency range, the antenna supports multiple 4G LTE and 5G Sub-6 GHz bands while delivering up to 30 dBi gain through its 900 mm precision parabolic reflector.
Compared with the 600 mm version, the larger reflector provides higher gain and narrower beamwidth, making the RF1742-9030D particularly suitable for long-range wireless links where link budget and directional performance are critical.
30dBi High-Gain Directional Performance
The RF1742-9030D provides 30 dBi antenna gain with a front-to-back ratio of ≥32 dB.
Its narrower radiation beam concentrates transmitted and received RF energy toward the target direction, helping extend communication distance and reduce interference from surrounding wireless systems.
The antenna features:
- HPOL beamwidth: 5–13°
- VPOL beamwidth: 2–5°
- Front-to-back ratio: ≥32 dB
- Cross-polarization isolation: ≥28 dB
These characteristics make it particularly suitable for fixed directional wireless links.
Wideband 4G and 5G Coverage
The antenna operates continuously from 1710 MHz to 4200 MHz, supporting a broad range of wireless communication systems.
Typical supported applications include 4G LTE Band 1, Band 3 and Band 41 as well as 5G Sub-6 GHz networks including n78, n79 and C-Band applications.
The wide operating range makes the antenna suitable for network integrators, telecommunications infrastructure projects and private network deployments that may operate across different frequency bands.
Dual-Linear Polarization
The antenna incorporates horizontal and vertical linear polarization into one antenna system.
This dual-polarized configuration is suitable for wireless radios using dual RF ports and MIMO architectures, while ≥28 dB cross-polarization isolation helps maintain separation between the two polarization channels.
Designed for Long-Range Wireless Links
The combination of a 900 mm reflector, 30 dBi gain and narrow beamwidth makes this antenna suitable for applications where greater communication distance or stronger link margin is required.
Typical applications include:
- Long-range point-to-point wireless links
- 4G/5G base station backhaul
- Private LTE and 5G networks
- Remote broadband connectivity
- Mining communication networks
- Forest monitoring networks
- Border and remote outpost communication
- Emergency communication systems
- Industrial wireless infrastructure
- High-capacity wireless bridging
Outdoor Installation
The RF1742-9030D is designed for fixed outdoor directional installations and supports universal pole mounting.
Its outdoor mechanical design supports 180 km/h wind loading and wind survivability of up to 200 km/h (125 mph), providing additional reliability for elevated antenna installations and exposed outdoor communication sites.
