Rejects pick-up noise from the antenna feedline by removing ground loops.

- Specifically recommended to work with SDR radios.
- Suitable for analogue radios.
- Indoor use.

The indoor broadband antenna galvanic isolator allows isolate the antenna galvanically from the receiver; only magnetic signal is coupling from the antenna.
Ground loops in SDR radios induced by the antenna feeder are very common if the computer ground is connected to the radio system increasing local background noise.
This type of ground loop issue can be solved by using galvanic isolation between the receiver earth system and the antenna earth.
In most station installations the antenna coaxial feeder is connected to mains earth at the receiver side. This can cause mains noise to enter into the receiver because either the feeder mains earth line is the return path for the antenna or noise being coupled to the antenna and radiated.
The Antenna Isolator can achieve up to 40dB noise rejection, depending on installation.

USB Galvanic Digital Isolator datasheet

Suitable for SDR radios, on ultrasonic applications and audio systems.

 The Audio Line Galvanic Isolator removes inherent ground coupling noises providing isolation between input/output unbalanced connected interfaces. It is a differential responding high common mode rejection device that removes Hum and Buzz artifacts enhancing signal quality by reducing spectral contamination due RF interference.
On Software Define Radio applications where a computer sound card is used to sample I/Q signals, ground loops are very common through receiver between USB connection and sound card (spikes on screen) This kind of ground loop issue can be solved galvanically isolating the path between the receiver I/Q outputs and the sound card inputs.
The Audio Line Galvanic Isolator is built around two broadband high linearity, low distortion, MIL spec broadband transformers. Transformers make excellent ground isolators. They transfer signal voltage from primary to secondary without any electrical connection between them breaking the path of the noise current that would otherwise flow between interface devices.
The Audio Line Galvanic Insulator is shielded in metal case. In addition internal transformers are covered with μ-metal EMI shielding case that virtually eliminate any electromagnetic interference from nearby sources.
Input/output connector ports are Rean-Neutrik Tiny XLR improving the device shielding due their high noise immunity and EMI protection. The socket free rugged locking mechanism provides secure and reliable connection.
Input and output device ports can be configure by means of jumper links:
