ARO1037 Omnidirectional Broadband Antenna 690-2700 MHz for 2G-5G, GSM-R and FRMCS

Q: Where is ARO1037 typically installed in tunnel projects?

It is commonly used outside the tunnel as a broadband donor antenna at tunnel portals or end-of-line sections, feeding repeaters or DAS equipment. It is also suitable for service galleries, emergency exits, technical rooms and station areas where mixed indoor/outdoor coverage is required.

The ARO1037 is a broadband omnidirectional antenna engineered to provide stable 360° radio coverage from 690 to 2700 MHz. This continuous operating range supports the evolution of mobile networks from legacy services to modern LTE/4G and 5G deployments, while also covering UMTS, GSM, GSM-R and FRMCS use cases within the same infrastructure.

In tunnel-related projects, this model is typically selected outside the tunnel as a donor antenna and as a broadband pickup point for tunnel portals / end-of-tunnel areas and end-of-line railway sections, where a clean omnidirectional field is required to feed repeaters or DAS equipment. The same approach is valuable for service galleries, emergency exits, technical rooms, utility corridors, as well as stations and metro stops where mixed indoor/outdoor coverage is needed without changing antenna type.

The antenna is designed for demanding telecom sites thanks to its full radome solution, compact dimensions and low wind impact, making it practical for pole installations on outdoor masts and building structures. The vertical polarization and omnidirectional pattern help maintain consistent coverage around the installation point, simplifying multi-operator and multi-technology upgrades across common bands such as 700/800/900 and 1800/2100/2600 MHz, where 5G capacity extensions are frequently implemented alongside 4G services.

Note: return loss/VSWR and gain versus frequency are provided as plots in the official datasheet; this enables quick verification against the exact band plan of the site before commissioning.

Frequently asked questions about ARO1037

Quick answers for tunnel-related donor use, repeater/DAS integration and broadband 2G–5G network upgrades.

Where is ARO1037 typically installed in tunnel projects?

It is commonly used outside the tunnel as a broadband donor antenna at tunnel portals or end-of-line sections, feeding repeaters or DAS equipment. It is also suitable for service galleries, emergency exits, technical rooms and station areas where mixed indoor/outdoor coverage is required.

Why choose an omnidirectional antenna instead of a directional one?

Omnidirectional coverage is ideal when the target area surrounds the installation point (360°), when the donor signal can arrive from multiple directions, or when you want one antenna to support multi-operator, multi-technology upgrades without re-aiming the antenna.

Does ARO1037 support 5G as well as LTE/4G?

Yes. The wide operating range (690–2700 MHz) is designed to cover legacy services and modern deployments including LTE/4G and 5G, alongside UMTS, GSM, GSM-R and FRMCS applications, depending on the band plan of the network.

Is a flame retardant radome required for my installation?

For installations inside tunnels or in areas with specific fire-performance requirements, projects may specify a flame retardant radome. ARO1037 is supplied with a full protective radome as per datasheet; if the project requires a flame retardant solution, select a dedicated tunnel antenna model/options specified for that requirement.
