Ferric snap on bead filter effective over frequency ranges specific to solar installations including PV solar arrays, inverters, optimizers, combiners and network related control devices.

Effectively suppresses Radio Frequency Interference under 300 MHz. Use for solar installations of AC, DC, data and Ethernet cables for reducing common mode currents creating interference in electronic devices.

Two separate halves, bind together with cable ties or heat shrink.

Typical use for large bundles of positive/negative wire where diameter of all cables is < 1.5"

THE RFI KIT FILTERS ONLY SUPPRESS COMMON MODE CURRENT (SIGNALS) THAT ARE COMMON TO ALL WIRES IN THE CABLE, AND DOES NOT EFFECT INDIVIDUAL DIFFERENTIAL SIGNALS ON EACH WIRE. THE FILTERS HAVE NO EFFECT ON THE NORMAL SIGNALS CARRIED WITHIN THE CABLE.

16:1 Baluns are useful between 750-850 ohm balanced loads where the impedance at the  end of the feed line is 800 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

16:1 Ununs are useful between coax and long wires with a load impedance near 800 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 16:1 unun and it may provide a better match than 9:1 ununs – this means quieter noise levels and stronger signals so you can hear distance stations easier.
