Product Information
  • Overview
 

Galvanic Antenna Isolator GI1000

The Galvanic Antenna Isolator GI1000 suppresses noise reaching the ground connections on the receiver. The GI1000 covers a wide-band range of 50 kHz – 1 GHz (typ. 1,5dB insertion loss). This unit can be used in many receiving applications, It will also work with frequencies up to 1,25 GHz but above 1000 MHz insertion loss may increase by up to 3db. The unit also has integrated double over-voltage protection and input and output are blocked for DC voltage.

The galvanic isolator GI1000 separates the path of the direct current between the outer shield of the coax cable and the shielding of the antenna feeding line in order to suppress interference caused by potential differences. This is achieved by using a small toroidal transformer. The inner conductor of the coax cable is insulated with capacitors providing coarse and fine voltage surge protection.

Close connection please

The GI1000 should be connected to the receiver as closely as possible to avoid other interference. We offer short very adapter cables with different connectors.
