Ham Radio RFI Feedline Choke

This powerful choke is designed to eliminate major RFI interference. It can be used in conjunction with amplifiers or even placed at the base of antennas. Frequency Range: 1MHz to 300MHz. Power Output: 1,500W SSB, 1,000W Digital.

These are made with male and female adapters on each end so they can simply be placed directly into any Feedline with no use of adapters! This RFI feed line choke is meticulously crafted using only the finest materials. They are free from any Chinese parts sourced from Amazon.

All ferrite used is Fair-Rite brand mix 31, directly sourced from the supplier. Genuine Messi & Paoloni heavy-duty soldered-on connectors are employed for all coax connections, and the coax itself is Messi & Paoloni, sourced directly from Italy.

These adapters are actually removable and re-usable by desoldering. Even the heat shrink tubing is USA-made and top-notch. If you're seeking an affordable solution to combat RFI, you'll need to look elsewhere. Frustrated by the numerous ineffective knock-off ferrite and RFI-blocking products available, I decided to create something of the highest quality and craftsmanship.

I wanted to ensure that no aspect was compromised. The quality is evident in the exceptional performance of these chokes, which are truly a work of art! Each choke undergoes rigorous testing using a common mode test rig and a high-quality VNA to measure the decibel drop (as shown in the charts). Unlike others, I use a top notch Nano VNA (2NN-SA) along with a Halibut Electronics RF test rig made specifically for testing true RFI on the outside of the coax.

All products are thoroughly tested after production. Please feel free to verify my identity through my call sign.
