Messi & Paoloni Ham Radio RFI Chokes for POTA or Shack

High-Performance RFI Chokes by KF8ASE

Built with Genuine Messi & Paoloni Components – Trusted by Hams Who Know Quality

Are you tired of cheap, ineffective RFI solutions? I was too — so I built something better. I’m offering two premium RFI feed line chokes designed specifically for POTA, SOTA, and Ham Shack operations. Both are hand-built with unmatched attention to detail and made from only the finest materials — no corners cut, no knock-off parts.

🔹 POTA / SOTA RFI Choke –

This compact, portable choke is ideal for field use. Whether you’re activating a park or working a summit, it helps reduce common mode current and line noise — giving you a cleaner signal and more successful contacts.

📡 Frequency Range: 1–300 MHz
🔊 Power Rating: 300W SSB / 100W Digital
🔌 Connection: Inline Male-to-Female – no adapters needed
🏕️ Ideal for: POTA / SOTA / Portable HF setups


🔹 Super RFI Choke –

(optional high-power heatsink upgrade)

This high-performance choke is engineered for serious shack or amplifier use. Use it at your transceiver, amplifier, or antenna base to significantly reduce RFI and protect your gear.

📡 Frequency Range: 1–300 MHz
🔊 Power Rating: 1,500W SSB / 1,000W Digital
🔌 Connection: Inline Male-to-Female

🔹 QRP RFI Choke – Lightweight BNC Model —

Perfect for portable and QRP operations, this compact RFI choke is built with the same uncompromising quality as our full-size models—just scaled down for your lightweight, portable, low-power needs.

Designed using premium Messi & Paoloni Airborne 5 coax and ultra-low-loss .200 BNC connectors (male to female), this choke is ideal for 1–30 MHz HF applications. Inside are high-performance Fair-Rite ferrite beads selected specifically for maximum suppression of common-mode current in a QRP-friendly form factor.

Whether you’re activating parks, operating field day, or just running a clean signal from your shack, this choke helps reduce RFI, audio feedback, and stray RF—without adding bulk to your setup.
