Gamma-150: interference-resistance figures in dB are not antenna gain

The application

The Gamma-150 table specifies 115 dB with one interference source and 95 dB with seven. These are resistance figures accompanied by an interference-source count, not antenna gain in dBi. Comparing the single dB number with gain of an ordinary navigation or radio antenna can create an incorrect specification.

Agree these details before ordering

Before ordering, agree the conditions for using the ratings, the navigation data chain and the connections. Gamma-150 has eight elements, 24 V power and maximum consumption of 20 W. The operating range is −40…+70 °C and maximum mass is 2.4 kg; these also belong in the selection.

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.
