Gamma-100: include the antenna in the power-system calculation

NavCom Gamma-100
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-100 interference-resistant GNSS antenna and its integration requirements.

The application

Consider antenna power together with every other load in the installation. Gamma-100 is specified for 24 V and a maximum consumption of 8 W. This is a product rating, not a complete calculation covering cable losses, other equipment and backup-power requirements.

Agree these details before ordering

The stated package includes a stabilized power supply. Agree its configuration and connection to the site system, and check the supplied 10 m cables against the actual route. Direct operation from 12 V, or compatibility with any external supply of a similar wattage, is not established by the source.

Reading the specifications

The model specifies 4 antenna elements, up to 3 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.
