2J7110B TETRA, UHF screw mount Antenna Big-Medusa N-F IP67/IP69

This high-gain antenna is engineered for public safety and critical communications, operating within the TETRA standard on the 400 MHz band. Its robust, heavy-duty housing ensures reliable performance in demanding environments, making it ideal for industrial, emergency services, and federal agency applications. The loaded dipole design maintains resonance across the 380–470 MHz range, delivering strong 360-degree signal coverage with high efficiency and peak gain. Typical use cases include critical communications, public safety, transportation, utilities, low power devices, and rapid deployment network solutions.

Connections

Connector & Cable

• Connector Type: N-Female

Installation / Environmental

The 2J7110B is designed with IP67, IP69 and IK09 rating giving it full resistance to water, dust and impact making it ideal for outdoor applications. The dome shape housing measuring Ø 96 × 130 mm, is manufactured with ASA UV stable material and has an aluminum alloy base with anti-rotation screw mounting. The N-Female connector is located at the center of the antenna base allowing for simple and secure antenna connection. This ground plane independent antenna includes an additional DC ground to offer additional protection against lightning strikes. This allows for continued antenna operation while in extreme weather conditions. All our products are designed and manufactured without hazardous materials while maintaining full REACH and RoHS compliance.
