Fish Finder – Sonar RFI Kit

Fish Finders/Sonar units can cause RFI “noise” in other electronic devices on a boat including audio and video systems, radar, SSB, wind/speed/depth instruments, etc. Likewise other electronic devices can also interfere with the fish finder and cause erroneous depth/temperature readings.

Palomar Engineers has developed a simple to install fish finder/sonar RFI suppression kit to solve the RFI noise problem aboard recreational and commercial boats.

Just slip a split bead on the transducer cable (1" ID) and use the 5 1/2" ID split beads on the fish finder/sonar readout unit transducer input and DC cables. Use the extra ferrites on other equipment needing protection like the Radar, radio, etc.

The high power ferrite impedance transformer series (> 1:1), configured with outputs to act as a baluns (unbalanced coax in to balanced load output) or as ununs (unbalanced coax input to unbalanced load output) are designed for demanding radio transmitter stations that run over 1,000 watts PEP or run continuous modes like AM, digital, RTTY, FM, etc. at high power levels. Radio contest operators, commercial shortwave broadcast, and industrial and commercial stations use these transformers for for a variety of balanced and unbalanced antenna loads.  Baluns are typically used for balanced loads and antennas like dipoles, loops, log periodics, and direct feed yagi/beams.  Ununs are used  with verticals, end fed wires, horizontal dipoles, G5RV/ZS6BKW, Zepps, vertical wire beams, etc).  All products are in an enclosed NEMA water resistant box with SO-239 input connector and stainless steel side/top studs with wing nuts or side and top eyebolts.  The enclosure box has mounting “side feet” for attachment to a post or antenna boom using nylon ties.
