Purpose. Simple, Effective RFI Kit consisting of 3 Solar Noise Filters (Mix 75) with 1/2" ID, for use on 3 Input/output ports such as Solar Panel Array input, Battery and Excess Load ports. Noise filters suppress noise and RFI at typical frequencies generated in solar charge controllers.
This kit is designed to choke common mode currents going into or exiting from your charge controller and they help keep common mode current out of the power line (or into your radio through the battery) which could cause interference to other devices connected to the same power line if not suppressed.
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.
If you use an inverter and experience RFI noise use additional mix 75 ferrite filters on the input and output of the inverter to help suppress this noise.Install both positive and negative wires through the same filter.
Generator RFI testimonial:
Bob Received your order in a timely fashion. Tried the generator kit on Sunday & it drops the noise from S9 to S5 and took out all the electrical noise. I may want some more toroids from you at some point for other interference problems I have here. Ken VE3KCY

Want to make up your own RFI kits for a particular operation? Here are links to some of typical RFI solutions used in portable operations:
If you use a computer for logging in your portable operations, RFI getting into computers will often lock up your computer and/or radio and a computer RFI suppression kits may be helpful
Make your expedition or portable operation a pleasant and fun outing and remember to take along your RFI kits so you have more time to operate rather then to troubleshoot intermittent or noisy receiver conditions.
Portable Antenna Kits
If you need an effective portable antenna which folds up for transport yet is easy to deploy at your operating site, consider the BULLET series of end fed wire antennas.
