Gamma-150: eight elements and thermal conditions

NavCom Gamma-150
Original illustration based on the series dimensional drawing. The source document does not show separate external housings for the two models.

A practical look at the NavCom Gamma-150 interference-resistant GNSS antenna and its integration requirements.

The application

Choosing Gamma-150 changes more than the number of elements. The specifications state eight elements, up to seven simultaneous interference sources, consumption up to 20 W and an upper operating temperature of +70 °C. More elements alone are not a sufficient selection criterion.

Agree these details before ordering

Check the temperature at the installation point and the separate storage range of −45…+80 °C. The supply remains 24 V and the maximum enclosure dimensions are 280 × 210 × 81 mm. Agree the integration requirements and documentation rather than transferring the smaller model’s specifications to this variant.

Reading the specifications

The model specifies 8 antenna elements, up to 7 simultaneous interference sources and 24 V power. Read resistance ratings together with the stated source count and agreed application conditions. These figures do not define antenna gain or a guaranteed operating radius.

Package and installation

The stated package comprises the antenna, a stabilized supply, a 10 m antenna cable, a 10 m power/data cable, mounting hardware and documentation. Series dimensions are 280 × 210 × 81 mm maximum. Agree mounting details, mating connectors and the data format for the actual equipment.

Questions and answers

Does this equipment suppress UAVs?

No. This description concerns the GNSS receiving path. UAV detection or suppression is not stated.

Does an RS-232 or RS-422 interface establish compatibility?

No. Agree the protocol, line parameters and interfacing equipment. The source does not provide a full list of compatible instruments.
