AC Power Filters — Eliminate Line-Borne RFI and Noise

Is your radio picking up a constant hum or hash — even with the antenna disconnected?
That noise could be coming from your AC power line. Modern electronics, solar inverters, switching supplies, and even LED lights can inject radio-frequency noise directly into your station through the power mains.

Palomar AC Power Filters block unwanted RF currents on the AC line, preventing them from coupling into your radio or accessories — and restoring a quiet background to your receiver.

When to Use an AC Power Filter

• You hear hash or humming on multiple bands even when your coax is disconnected.
• Noise increases when household appliances, solar inverters, or lighting systems turn on.
• Your station shares a circuit with other electronic equipment.

If any of these sound familiar, you need an AC Power Filter between your wall outlet and equipment.
