RFI Solution Kits
RFI / EMI Solutions — Signal Clarity Starts Here
Eliminate unwanted noise, hum, or interference before it reaches your radio, audio, or data equipment.
From 100 kHz to 1 GHz+, Palomar Engineers offers engineered RFI / EMI suppression solutions to protect your gear, improve signal clarity, and restore quiet to your station.
We’ve been designing ferrite-based noise filters and common-mode chokes for more than 50 years — delivering proven performance to amateur, marine, commercial, and industrial applications worldwide.
Choose Your Noise Path
Every RFI or EMI problem has a path — and that’s where the cure begins. Select the category below that matches your type of interference:
| Category | Applications | Typical Products |
|---|---|---|
| Feedline & Coax Chokes | Stops common-mode noise traveling on coax shields; reduces RFI in HF/VHF stations and improves receive quietness. | Explore Coax Noise Filters › |
| AC / DC Power Line Filters | Blocks line-borne noise from AC mains and DC switching supplies — a must for modern shacks and solar systems. | Explore Power Line Filters › |
| Smart Home / Broadcast / Industrial Kits | Comprehensive suppression kits for smart devices, audio studios, solar controllers, and marine or industrial systems. | Explore All Kits › |
Why RFI / EMI Suppression Matters
Interference isn’t just annoying — it masks weak signals, distorts data, and can damage sensitive electronics. Palomar Engineers tackles noise at its source by controlling unwanted RF currents where they travel: along coax shields, power leads, and control cables.
- Suppresses unwanted RF currents across 100 kHz – 1 GHz+
- Improves signal-to-noise ratio and receiver sensitivity
- Protects transmitted audio and data integrity
- Ideal for ham radio, broadcast, marine, solar, and lab environments
How to Find the Right Solution
- Identify the path your noise or interference travels — coax, power line, or control cable.
- Select the product category above that matches your situation.
- Install your filter or choke close to the source of the noise for best results.
