Gamma-100 equipment replacement: check the exact SKU

The application

A service enquiry should distinguish the new product from older equipment with a similar name. The interference-resistant Gamma-100 GNSS antenna has SKU 21381. A shared Gamma name does not establish interchangeability, pin assignments or the package needed to replace an old receiver or antenna.

Agree these details before ordering

List the retained devices, existing connections and observed fault. The new antenna is specified for 24 V, up to 8 W and four elements. Resolve integration from technical information; the stated maximum of three interference sources is not a substitute for interface compatibility.

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.
