proISO™ series

Product catalog summary

Introduction
The proISO™ series of Galvanic Coaxial Cable Isolators by Promarine Oy Ltd is designed to address ground leak and interference issues in communication systems, particularly in marine and military environments. These isolators enable the use of grounded antennas without the risk of stray currents and ground leaks, providing protection against conducted noise and interference.

Specifications
The proISO™ series includes universal isolators and models optimized for FM radio, TV antennas, high power MF/HF systems, and marine VHF. The proISO 1021 model is specifically designed for TV and radio antennas, isolating terrestrial broadcast TV antennas from the ship’s electrical ground system. It features inbuilt filtering against VHF/AIS and 450MHz LTE transmission.

GALVANICAL COAXIAL CABLE ISOLATOR prolSO™ series of Galvanical Coaxial Cable Isolators prolSO™ series of Galvanic Coaxial Cable Isolators for DC-grounded antennas solves immediately ground leak and interference problems in communication system. prolSO™ technology is designed especially for demanding marine and military environments. proISO™ series of Galvanic Coaxial Cable Isolators allows the use of ground plane-, lightning protected- and grounded antennas in vessels that would otherwise suffer from stray currents and ground leaks. proISO ™ series protects against conducted noise and interference. In addition to universal isolator, proISO™ series includes optimized models for FM radio and TV antennas, high power MF/HF systems and marine VHF. Due to high-performance design of proISO™ it can easily be used between antennas, filters, radios and amplifiers without losing sensitivity of the communication system. proISO™ technology enables trouble free EMP and EMC protection of coaxial cable inlets in the vessel's hull. If the cable's screen is grounded for potential equalization, EMC shielding or EMP protection, an unwanted DC current path might occur between the vessel's metallic body and radio communication equipment. By installing a proISO™ device just after the cable inlet a complete ground loop protection is achieved. No artificial floatings are required anymore. Prevent ground loops and increase performance • fast deployment in retrofits • suitable for all radios and antennas • static discharge protection • breaks ground loops • minimizes interference • fully passive construction • no wearing components • customized versions available • compact size with flexible cable connectors eases installation proISO 1021 vs. proISO 1020 proISO 1021 75ohm Galvanic Coaxial Cable Isolator for TV and Radio antennas is specially designed to isolate terrestrial broadcast TV antennas (DVB-T, DVB-T2, ATSC, ISDB-T, DMB-T/H, NTSC, PAL, SECAM) from the ship's electrical ground system. In addition to model 1020 it has inbuilt filtering against VHF/AIS transmission and 450MHz LTE transmission.
