Clamp made of fiberglass reinforced also in the flame retardant version that does not compromise the electrical characteristics and the radiation pattern of the antenna on which it is mounted.

This catalogue groups Protel directional antennas operating in the 690-960 MHz range, widely used for low-band cellular coverage and railway communications. In modern networks, these frequencies are strategic for penetration, long corridors and underground environments, supporting LTE/4G and also 5G low-band deployments (commonly associated with 700/800/900 MHz layers depending on the country and the operator roadmap).

Typical applications include road, highway and railway tunnels, metro lines and underground stations, service corridors and complex indoor areas where multipath, reflections and harsh installation conditions require predictable and controlled RF behaviour. In these scenarios the system architecture often includes DAS head-ends, repeaters / microrepeaters and dedicated donor antennas, with careful management of isolation and stability.

Antennas in this family are generally selected by propagation scenario and installation constraints:

Shrouded Yagi and tunnel directional antennas to concentrate the signal and reduce unwanted reflections.
Log-periodic and broadband directional antennas for multi-operator or multi-service coverage strategies.
Panels / sectors for portals, stations and outdoor corridors where controlled sectorisation is required.
MIMO-ready configurations when required by LTE/5G network designs and DAS architectures.

Many tunnel and transport infrastructures require protective solutions in addition to RF performance. Depending on the antenna model, a fiberglass radome may be available, including an optional flame retardant version for additional safety constraints.

For a broader overview of this frequency range and its use in LTE, GSM, GSM-R and FRMCS projects, including tunnel and corridor applications, see the technical insight on 690–960 MHz mobile and railway antennas .

Frequently asked questions about 690-960 MHz tunnel antennas

Answers to the most common questions about low-band antenna selection for tunnels, DAS and railway/mobile coverage.

Does 690-960 MHz include 5G use cases?

Yes. This range supports low-band network layers often used for LTE/4G and also for 5G low-band strategies (commonly associated with 700/800/900 MHz layers depending on local spectrum plans). It is especially valuable for penetration and long corridors, which is why it is frequently selected for tunnels and underground infrastructures.

When should I use a donor antenna in a tunnel system?

Donor antennas are typically used to capture a stable outdoor signal feeding repeaters or DAS head-ends. In tunnels, correct placement and sufficient isolation are critical to prevent oscillation and to keep the system stable under multipath conditions.

Which antenna type is usually preferred for tunnel coverage?

Shrouded Yagi and directional tunnel antennas are frequently chosen to control reflections and concentrate energy along the path. Log-periodic and broadband solutions are often selected when multi-service or multi-operator coverage is required.

Why choose a fiberglass radome with flame retardant option?

In harsh environments such as tunnels and transport infrastructures, a fiberglass radome improves mechanical protection and long-term stability. The optional flame retardant version can be selected when the installation requires additional safety constraints.
