GROUNDING PROTECTORS prolSO™ series of Grounding Protectors for dGPS and Navtex antennas and MF/HF applications are professional high-quality isolators. prolSO™ grounding protectors create galvanical isolation between active antenna element and vessel's ground. prolSO™ technology is designed especially for demanding marine and military environments. prolSO 2001 is used to replace grounding wire of dGPS/Navtex reception antenna. It creates DC- isolation between active antenna and vessel's ground while still ensuring RF ground connection for interference free reception of received signals. prolS02003 and 2004 are grounding protectors for MF/HF communication systems. The model 2003 can be used to isolate MF/HF radio transmitter and model 2004 is specially designed for MF/HF antenna tuner grounding. They work on all kind of MF/HF communication systems including power fed Antenna Tuner (ATU) units. prolSO™ series of grounding protectors does not only prevent the formation of harmful ground leaks but it also works as lightning protector and dissipates harmful static charges from antenna elements. proISO™ technology enables trouble free galvanic isolation of communication system. Due to its high performance and innovative design, safety is never compromised and the quality of communication is secured. • fast deployment in retrofits • replaces antennas'ground wire • static discharge protection • breaks ground loops • enables lightning and surge protection • makes EMP and EMI protection easy • fully passive construction • compact size with flexible cables eases installation Electromagnetic modelling services fine-tunes performance By using advanced proEMS™ electromagnetical simulation, modeling, analysis and measurement services a complete 3D-electromagnetic environment of the ship's external structures is built and the optimal location for each antenna with the least interference can be found and verified. The proEMS™ services are useful for any size of boat or ship and are tailored for each customer separately.
