Sector Antenna

Shenzhen Qianmu Communication Technology Co., Ltd. is a professional China sector antenna Manufacturer in China, with its own production Factory and global one-stop Supplier. It independently researches, develops and produces a full range of high-gain directional sector antennas covering the entire communication frequency band of 698-3800 MHZ. Compatible for operator base stations, park WiFi coverage, construction site wireless Bridges, factory area Internet of Things data transmission and other engineering scenarios. With its own radio frequency anechoic chamber and automated assembly line, all antenna are factory-tested for standing wave, gain, high and low temperature, and waterproofing, and a full set of test reports can be issued with the goods. OEM/ODM band, beam Angle, interface customization is supported.

How it works

The entire structure follows the principle of directional beam focusing: The aluminum alloy reflector back plate, multiple microstrip oscillator arrays, sealed waterproof antenna cover, RF feed line, adjustable mounting bracket.

1. The oscillator array sends and receives electromagnetic waves in different frequency bands, and the metal backplate reflects useless reverse signals, enhancing the front-to-back ratio; The measured front-to-back ratio is ≥25dB in the same environment, and the clutter interference is reduced by 65%;

2. Beam Angle physical constraints: The 120° standard model radiates energy only to the forward sector area and does not leak signals to adjacent areas. Measured in dense urban area networking, the network throughput of adjacent cells increased by 42%;

3. Dual-polarization ±45° cross oscillator design, compatible with MIMO multipath transmission, terminal device connection rate increased by 35% at the same transmission power;

4. The housing is made of UV-resistant UPVC material, with no metal shielding loss. The RF performance fluctuation in the -40 °C to +85 °C range is ≤0.3dBi, and the signal attenuation is minimal for long-term outdoor use.

Core Selling Points

Bulk purchase of 1000-mesh communication sector antennas helps address the pain points of large outdoor networking, including interference, short coverage distance, outdoor damage, and high engineering construction costs. The five core advantages are compatible with various communication projects:

1. High-Gain Directional Focusing

With 8–18dBi gain options, the long-range wide coverage sector antenna provides extended coverage. Compared with ordinary omnidirectional antennas, the coverage radius is increased by 70% at the same transmission power. No dense deployment is required in mountainous areas and open factory areas, reducing engineering equipment investment.

2. Beam Controllable Anti-Interference

With available 60°/90°/120° multi-beam angles, the antenna provides precise division of signal coverage areas and stable networking in high-density scenarios. It avoids signal cross-interference, lag, and disconnection in high-density Internet access environments such as office clusters, residential areas, and campuses.

3. IP67 Fully Sealed Outdoor Weather-Resistant Structure

The antenna adopts a one-piece injection-molded waterproof cover with sealed joints, which is resistant to rainstorms, snow, and coastal salt spray corrosion. The wind resistance level reaches 60m/s, supporting outdoor pole installation for 5 years without leakage or aging failure.

4. Adjustable Universal Mounting Bracket

The antenna is equipped with a stainless steel pole mounting bracket, providing strong engineering adaptability. It supports up-and-down inclination adjustment and 360° horizontal fine adjustment, suitable for various mounting carriers such as communication towers, electric poles, building facades, and steel structure factories.

5. Source Factory Full-Dimensional Customization Service

As a professional sector antenna factory, it supports band trimming, beam angle customization, N/SMA/BNC/Fakra interface replacement, cable length customization, customer logo silk-screen printing, and quick sample testing for small batches.

Application Scenarios

1. Operator Cellular Base Station Coverage

Mobile, Unicom, and Telecom base station towers use sector antennas for batch deployment. The 120° beam segmentation divides the 360° signal area to reduce inter-cell interference. Long-term bulk purchases support dozens of county-level communication transformation projects across the country.

2. Full WiFi Coverage in Industrial Parks and Factories

Pole installation in large manufacturing plants, logistics parks, and warehousing areas solves weak IoT signal problems for workshop equipment and open-air storage yards. Multiple enterprises have measured that the terminal online rate in factory areas increased from 62% to 98%.

3. Public Wireless Networks in Campuses, Communities, and Scenic Areas

Deployed on residential rooftops and the highest points of scenic areas, the antennas provide wide coverage for households and tourists, replacing a large number of small omnidirectional APs and reducing later operation and maintenance costs by 50%.

4. Wireless Monitoring Bridges for Mines and Construction Sites

Remote video transmission from mountainous construction sites and open-pit mines is supported by directional high-gain performance. The signal can penetrate light obstructions, providing stable and uninterrupted monitoring signals at tunnel entrances and slopes.

5. Signal Blind Spot Projects in Urban, Rural, and Mountainous Areas

The antenna enhances 4G signals in remote villages, towns, and mountainous roads. When used together with repeater stations, it helps solve problems such as mobile phones without network access and positioning loss for ride-hailing vehicles.

Standardized Installation Guide

1. Pole mounting bracket: Lock the matching stainless steel clamp bracket onto the communication pole/pipe, leaving room for up and down adjustment;

2. Mounting the sector antenna body: Insert the antenna back buckle into the bracket slot and initially tighten the fixing bolts;

3. Beam Angle calibration: Rotate the antenna horizontally to align with the target area according to the coverage area orientation, and adjust the downtilt Angle vertically to match high and low coverage;

4. Rf cable docking: Align the N-type connector with the base station /AP device interface and tighten it. Wrap the connector with waterproof tape for sealing.

5. Overall reinforcement and re-inspection: Re-tighten all bolts, check that the antenna is not loose and the cable is not pulled, and complete the outdoor deployment

FAQ Frequently Asked Questions

Q1: Will the sector antenna get wet or damaged when used outdoors for a long time?

A1: No. The entire unit adopts an IP67 one-piece sealing structure. The antenna cover seams are sealed with waterproof glue, and the RF connectors are equipped with waterproof tape. It has passed continuous spray waterproof tests before leaving the factory and will not leak during heavy rain or high-pressure cleaning. It is suitable for year-round outdoor deployment.

Q2: Can the frequency band, beam angle, and LOGO of the antenna be customized?

A2: Yes. As a source factory, we support customization of band trimming, beam angle adjustment, cable length, interface type, and customer brand LOGO silk-screen printing on the enclosure according to specific requirements, meeting personalized engineering and foreign trade OEM needs.
