Gamma-100: why a GNSS antenna does not replace a two-way radio antenna

The application

For a vehicle or a site, separate radio communication antennas from satellite navigation equipment. Gamma-100 uses the stated BDS B1, GPS L1, GAL E1 and GLO G1 bands. Its ratings do not describe a two-way radio transmitter, voice range or group radio coverage.

Agree these details before ordering

Agree 24 V power and RS-232, RS-422 or Wi-Fi integration with the navigation installation. Four antenna elements and up to three interference sources remain specifications of this separate product. Connection to a particular radio or coordinate-display system needs its own compatibility confirmation.

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.

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.
