Why is AR1024B suitable for tunnel coverage?

AR1024B combines high gain (17 dBi max.) with a narrow radiation pattern (typ. beamwidth 15 deg H / 18 deg E), helping engineers control the serving area in tunnels and radio corridors and improve link budget where signal must be guided along confined environments.

Is a flame retardant radome available for this antenna?

Yes. An optional VTR fiberglass flame retardant radome is available (AR1024BRI), supporting projects where flame retardant material specifications are required.

How is lightning protection managed on AR1024B?

All metal parts are D.C. grounded, providing an electrical grounding reference that supports installation safety and helps protect connected radio equipment.

Q: Which services are typically covered by AR1024B in the 1710-2170 MHz range?

The 1710-2170 MHz range is commonly used for DCS 1800 and UMTS 2100, and it is widely adopted for LTE (4G). Depending on the operator band plan, the same spectrum can also be part of 5G deployments in the 1800/2100 MHz ranges.

Q: Can AR1024B be used as a donor antenna outside tunnel portals?

Yes. In repeater and DAS architectures, a directional high-gain antenna can be used as a donor antenna at outdoor or portal-facing positions to capture the serving cell and feed the system, improving control versus unwanted pickup.

Q: Which connectors are available on AR1024B?

The antenna can be supplied with 4.3-10 female or 7/16 female connector, according to the ordering code.

High-gain dual-band Yagi for 1800/2100 MHz tunnel radio corridors

AR1024B is a broadband, high gain directional Yagi antenna covering 1710 to 2170 MHz, a core range for DCS 1800 and UMTS 2100 services and widely used for LTE (4G). According to the operator band plan, the same 1800/2100 MHz spectrum can also support 5G deployments, making this antenna a solid choice for modern multi-technology radio infrastructures.

Designed for tunnels and demanding outdoor environments

Developed for motorway, railway and metro tunnels, AR1024B provides a narrow, controlled radiation pattern (typ. 15° H / 18° E) to help engineers manage corridor coverage where reflections and long propagation paths challenge radio stability. The protective fiberglass cover supports deployments in harsh climatic conditions, where mechanical reliability and long-life performance are essential.

Portal-facing and donor antenna role for repeaters and DAS

In repeater and DAS architectures, AR1024B can be installed outdoors at tunnel portals or on suitable masts as a donor antenna, capturing the serving cell with controlled directionality and feeding the system with an improved link budget. This approach is frequently adopted to extend LTE/5G services into shielded environments while keeping unwanted pickup under control.

Safety-oriented details: DC grounding and flame retardant radome option

D.C. grounded structure: all metal parts are D.C. grounded to support lightning protection and to help protect connected radio equipment.
flame retardant option: the antenna can be supplied with the AR1024BRI VTR fiberglass flame retardant radome, matching typical tunnel procurement and safety requirements where specified.
Connector flexibility: available with 4.3-10 female or 7/16 female connector to match installation standards.

Antenna designed and manufactured in Italy.
