AR1022 is a shrouded high-gain Yagi engineered for demanding tunnel coverage where the radio path is long and controlled directivity is needed. Typical tunnel deployments include railway and high-speed rail corridors, motorway and road tunnels, and metro infrastructures where a focused beam helps shape coverage along the tunnel axis and supports repeatable performance.

The antenna covers 790÷960 MHz and 1710÷1880 MHz, ranges widely associated with LTE/4G (e.g., 800/900/1800), GSM/2G and GSM-R (around 900), and also commonly reused by 5G deployments in low/mid cellular layers (depending on national/operator frequency plans). With typical gain 16/16.5 dBi and narrow beamwidths, it is suited to tunnel systems where high gain is a priority.

For installation flexibility, two connector versions are available: AR1022.1 with 2 x 7/16 female connectors and AR1022.C with 1 x 7/16 female. The fiberglass full radome provides mechanical protection (ice protection) and all metal parts are D.C. grounded for robust operation in real field conditions.

Antenna designed and manufactured in Italy.
