A11-V43-121

Overview

The Nextivity A11-V43-121 is an indoor omni-directional dome antenna designed for cellular signal distribution. It operates within a frequency range of 698–5900 MHz, supporting 3G, 4G, and LTE bands. The unit features a 50-ohm impedance and horizontal polarization with a gain of 2–5.5 dBi. It utilizes an N-type female connector and includes a 1-foot cable. The VSWR is rated at ≤2.0, with a vertical beamwidth of 85°±30°. The antenna mounts via a threaded bolt through an 18 mm hole.

Feature Summary

• Provides 360-degree omni-directional signal reception and transmission for indoor environments
• Supports wideband cellular frequencies from 698 to 5900 MHz
• Designed for ceiling mounting using a standard 18 mm diameter hole

Applications

• Indoor server antenna applications for cellular repeater systems
• Wide area coverage in commercial buildings
• Integration with Cel-Fi signal boosting units

Procurement Notes

Verify the connector type matches system requirements; this specific model uses an N-type female interface. Confirm that the operating frequency range covers all target cellular bands for the installation site. Ensure the mounting surface accommodates the required 18 mm hole diameter for secure installation.

Selection Notes

Select this model when wideband coverage across multiple cellular generations is required for indoor deployments. It is suitable for SISO configurations where omni-directional radiation patterns are necessary. Consider the 1-foot cable length for proximity to the donor device or amplifier unit.
